030031032033- I have a ZipGS. Sometimes my GS 'hangs' on power-up. Why? The speedup has led to system crashes. What's the problem? A new accelerator board has led to crashes. What's the problem? How can I get a display of IIgs speed? From: Marc Sira, David Empson, Rubywand 001- What are the correct settings for a ZipGSx? I've tinkered with "CPS Follow", "Counter Delay", and the like but have no idea what I'm actually doing. Bank C/D Cache Enable-- Leave this at the default setting (SW1-1 set to ON).
SW2-1 through SW2-7 set access speed for Slots 1-7. Set the switch OFF for slower access to the corresponding Slot. This is generally only needed for a small number of cards that are speed critical but not IIgs-aware. 5.25" disk interface cards are covered by the CPS FOLLOW option (1-5) if they are in slots 4 to 7. I have found that it is necessary to enable the delay for slot 6 when using a 3.5" drive connected to the IIgs disk port.
at full speed (set ON) or "normal" speed (set OFF)**. SW2-8 sets Defeat Speaker Delay. To play 'old Apple' music and effects correctly, the switch should be OFF to permit the delay. **Note: Whether or not a particular card can work without a slow-down is something you can determine by experimentaton. This is easiest using the ZipGS CDA accessed via the Desk Accessories menu (OpenApple-Control-Escape). The CDA settings are not permanent.
______________________________ From: Jeff Brielmaier 003- How do I set up a Transwarp on my IIe? Bank1: Sw 1-7 -> Change to OPEN if there is a memory card that uses the "Langauge Card bank switching technique". (Normally CLOSED) Bank1: Sw 1-7 -> Change to OPEN if the plug in card must be accessed at 1 MHz (Normally CLOSED. OPEN for Floppy diskette controllers) Switch 8 on both Banks: Sets the power up speed of Transwarp Bank1 Bank2 3.6 MHz OPEN OPEN 1.
There is also a jumper pair near the bottom middle of the card. This is the Speed Jumper. Jumper it if you want 'demon to slow down for I/O accesses to Slots 4 & 5. (The 'demon always slows for Slot 6 I/O ($C0E0 - $C0EF.) According to the "Manual" (a folded card), pressing PDL-1 (Closed-Apple on a IIe) upon power-up will engage a self-test. Pressing ESC at power-up will turn OFF the card and allow running at normal speed.
OFF indicates slot/port is accessed at High Speed. ON indicates slot/port is to Slow Down for access. All slots that can be accessed at High Speed and all empty slots should have the corresponding Dip switch set to "OFF" (this is the non-bank switch setting). Special Note about Switch 4: Switch 4 on the SpeeDemon DIP switch no longer controls the access speed to slot 4. It now controls how the joystick and paddles are read.
Special Note: The slot that the SpeeDemon card resides in should be set to the "Off" position ____________________________ From: Will Baguhn 009- How can I get a 'Cache Hit' indicator for my ZipGSx? This latest ZipGSx modification is pretty straightforward. When I decided I wanted a Cache HIT light instead of a Cache MISS light, I went to Rat Shack and bought a pack of Green LEDs (I like green. Blue or Orange will work just as well.

From the usual BASIC prompt, get into the Monitor (e.g. CALL -151) and type in the following code to turn OFF the ZipGS ... 2000:A9 50 8D 5A C0 8D 5A C0 8D 5A C0 8D 5A C0 8E 5A 2010:C0 0A 8D 5A C0 20 00 BF 65 1D 20 00 00 04 00 00 2020:00 00 00 00 A 2000L should look something like this ...
The reverse is also true. If the controller feels that a lot of data needs to be brought in, it will cache the data, and, possibly, overwrite useful code, causing another slowdown when the code needs to be fetched again. With a split cache, the code and data segments no longer overlap. Caching code cannot overwrite data, caching data cannot overwrite code.
Reversing these changes is fairly easy. If you decide that the performance change was detrimental, simply desolder the wires that you installed, and solder in wires to replace the traces that were cut. I found that the split cache sped up my system notably, especially under the Finder and other desktop applications. Improvement was much less noticeable under text applications. (I haven't checked affect on compiling speed, yet.
____________________________ From: Frank M. Lin 014- What Oscillator freq corresponds to what TWGS/ZipGS operating speed? For TWGS and ZipGS, the crystal oscillators runs at 4 times the speed of the 65816. Below is a chart showing osc and corresponding TWGS or ZipGS speed. Osc Frequency MHz 28 32 33.3333 36 40 42 46 48 50 55 60 TWGS/ZipGS Speed MHz 7 8 8.3333 9 10 10.5 11.5 12 12.5 13.75 15 My understanding is that, if you over-clock a CPU. It just won't function. You can't damage it.
TranswarpGS uses an 8-pin socket intended for holding a half size oscillator module (picture D). Make sure the module is oriented with the marked end (usually having a dot, squared corner, and/or notch) facing upward. Make sure the module is oriented with the marked end (usually having a dot and/or notch) facing upward. The lower two pins of the module should be in the lowest two pins of the socket. WARNING: The oscillator may be damaged if installed incorrectly.

oscillator), which will make a 12.5MHz Zip. The oscillators are cheap enough to get two or three for experimenting with higher speeds. So, you just plug your Tag and Data RAM chips into the Digi-Key adapters and plug the adapters into the Tag and Data sockets of the Zip. Then, you install the new 65C816 and oscillator and make sure DIP switch 1-7 and 1-8 are both set OFF (for 64k cache). That's it, done completely without soldering. ZipGS boards vary. On some you may be able to go above 12.
John Link charted some comparisons in 1991 involving nine setups: no-TWGS, and 7, 8, 9, 10mHz boards before and after the 8kB-to-32kB cache upgrade. He used three benchmarks: 1. time to calculate page breaks in a 218-page Appleworks document 2. time to scroll through a 39-page Awks-GS document 3. time to compile 4800 lines of MD-BASIC source code For a 7mHz 8kB TWGS, the speed gain for the 32kB cache upgrade is roughly 33% to nearly x2.5 plain GS speed.
TransWarpGS boards vary just as do ZipGS boards. Some can be pushed to higher speeds than others. If you decide to do a speed upgrade, get two or three oscillators to allow for some experimentation. For a step-by-step guide, download Scott G's TWGSupgrade.SHK. HyperCard stack. (See Q&A 019 above) ______________________________ From: Wayne Stewart I have a TransWarpGS with rev A GALs and a rev 1.5 ROM. It came as 7mhz with an 8k cache.
______________________________ From: Sandy 025- How can I tell the firmware version of my TWGS? CDA With the IIGS turned on, press CONTROL-Apple-ESCAPE And go to the Transwarp The ROM version will be displayed on the screen. ______________________________ From: Mitch Spector 026- Do I need I need the 2B GAL for my Transwarp-GS to use a SCSI interface? If I do, where can I get one? The TWGS-2B GAL was a DMA fix Applied Engineering issued for the board.
______________________________ 029- After installing my ZipGS along with the ZipGS CDA and other software I've noticed that my ZipGS settings never seem to match the ones I originally set via the onboard DIP switches!? There are two likely explanations. One is that your interpretation of the settings is confused due to the rather poor explanations provided in the Zip ondisk HyperStudio 'manual'.
slightly (naturally, with power OFF). You do not want any contact to normally touch a contact across from it. Whatever, if your GS starts okay and does not exhibit the same kind of hanging in the future, you know that the ZipGS card is well socketed.
033- How can I get a display of IIgs speed? You can use SpeedGS. This is a STARTUP program selector for ProDOS-8 on the Apple IIgs which features display of Boot Volume, Date/Time, and current Speed. Speed is shown as a rounded multiple of 'Normal'-- i.e. 1MHz. For download sites, see Csa21MAIN4.txt .

From: Rubywand, David Empson, and Michael Gährken 001- What Operating System environments does the GS support? The GS can support several. Some of the more popular OS environments include ... DOS 3.3- usually Beagle's Prontodos or some other speeded version of the original DOS 3.3. This is the 5.25" diskette-based disk operating system used for years on earlier Apple II's. It's commands are designed for use from BASIC programs or from the keyboard. Many old Apple II games and other wares are on 5.
Platinum Paint is a commercial program that can import all GS formats plus MacPaint. It can only save in SHR and Apple Preferred. Version 2.0 can make Animations too! ShowPic 6 is a shareware NDA that can display most GS formats. You can also save the resulting graphic as a IIgs SHR painting. SuperPac is a commercial program which can create/display SuperPac format compressed pics and pic pieces Dream Grafix supports all 3200 color picture types and also 16 color and 256 color pictures.

You can boot a decent System 5.0.4 or very modest System 6.0.1 from a 3.5" diskette. With two 3.5" drives, you can boot a decent System 6.0.
Copy Paintworks.Gold and the PaintTools folder (with its contents) to a folder on your hard disk. The Patch allows you to to start PWG under System 6 and use most PWG features. However, some Palette selection options will bomb the program.

I have a such a program at home. It's called QSO Kid.
______________________________ From: O Aaland 012- How can I use a Mac as a network server with my GS? In order to use the Mac as a server with a useable system folder you will have to have AppleShare version 3 running on the Mac. It sounds like you are wanting to use a local boot disk on the GS and then log on to the Mac to use tha Mac hard drive. This will work with file sharing active on the Mac. The disk you need to make for the GS is a Network: Local Startup and not a Network: Server Startup disk.
You probably cannot run AppleShare 2.x on an LC III, because it only runs under Mac System 6.x. Apart from the number of users, the full AppleShare server adds many useful features, such as administration tools, potentially acting as a print server, and faster performance. It ties up more resources on the machine than File Sharing. AppleShare is commercial, but you might be able to get hold of a cheap copy of version 3 from somewhere. As far as the multiple server option goes: that should work fine.
available, either. Sometimes, these programs include a built-in screen save feature; otherwise, capturing a screen will take special measures. One way to capture most otherwise un-grabbable super-res screens is via a ProDOS-8 super-res utility which can save the super-res screen. The utility must be one which does not, itself, change the super-res screen upon startup (e.g. Nibble's SuperPac or a save/disp program you write yourself). Make sure your Startup Slot is set to Slot 5. Start the game, etc.
Quite a few. Apple Integer BASIC (in-ROM on the first Apple II's), can be loaded into II+ and later models. Applesoft, a floating point BASIC, is in-ROM on all models starting with the II+. Older Apple II's can load-in Applesoft or, via a plug-in board, access it from ROM. The best way to write Applesoft BASIC programs is using Program Writer, a full-screen editor from Beagle Bros. Users who want to speed up their Applesoft programs can use a BASIC compiler such as TASC or Einstein.
______________________________ From: David Cross 017- How do I save a BASIC program in ASCII text form? The following line added to the front of your Applesoft BASIC program will save it in a Text file named "LISTFILE". It works in DOS 3.3 or ProDOS. 1 HOME:PRINT CHR$(4)"OPEN LISTFILE": PRINT CHR$(4)"WRITE LISTFILE": LIST 2,: PRINT CHR$(4)"CLOSE": END POKE 33,33: If you have a line 1 which you'd like to leave alone, you can enter the above at Line 0 and change LIST 2, to LIST 1,.
Actually, GEOS is ProDOS compatible, at least in the sense that Catalyst, MouseDesk, and Apple II Desktop are. GEOS can act as a program launcher for ProDOS programs. Obviously, for GEOS programs, GEOS acts like the full OS (much like GS/OS on the IIGS and MacOS on the Mac, actually), but it can do everything MouseDesk can do in regards to launching ProDOS programs. On the GEOS desktop, the files show up as icons stamped with "ProDOS; and, the user can copy and delete ProDOS files.
GS WorldView (v5.1) http://apple2.org.za/gswv/a2zine/Misc/ Complete documentation does not seem to be available on-line. You can find decent documantation at ... Aple II Text Files http://www.textfiles.com/apple/DOCUMENTATION/appleworks Gareth Jones's web pages http://modena.intergate.ca/personal/gslj/appleworks.
Using my Mac PPC, I just change the file type of any 5.25 DOS 3.3 disk image to this: New Type: New Creator: DSK5 Gus! Then, I drag and drop it over the icon of either Gus or Bernie. Both launch just fine for me in this way (assuming that the disk image is actually a boot disk). ______________________________ From: Beverly Cadieux 025- Is there a way to convert two-column Text to one column? Yes. AppleWorks version 3.0 with TimeOut TextTools will do this. First you have to install TimeOut.
______________________________ From: Rubywand 027- How can I move AppleSoft BASIC programs to Quick BASIC on my PC? Transferring Applesoft programs on an Apple II to QBASIC, GW-BASIC, etc. on the PC is mainly a matter of moving a text copy of the program to the PC. (To make a text copy of an Apple II program, you LIST the program to a Text file. See Q&A 017 above.) On the PC, you bring the A2 program text into your BASIC editor. BASICs available on a PC are not 100% compatible with Applesoft.
Mainly, the directions tell you to rename the _ON and _OFF files from .txt to .reg for executing.

Note 2: A version 1.01 ZipGS card needs to be upgraded to work with RamFAST. 2- External CD-ROM disc drive which your SCSI card supports. The Apple Hi-Speed SCSI card is known to work with ... Apple CD-150 Apple CD-600i Apple CD-SC+ Pioneer DRM-600. The RamFAST is known to work with many drives, including any "SCSI Standard" drive and practically any NEC or Texel. Some specific models are ...
4- To hear music played from a CD, Stereo headphones, speakers, or hi-fi cables need to be plugged into the CD ROM drive. Most drives have a mini- Stereo socket in the front. To fit the socket, the plug for your headphones, etc. must be a Stereo plug. 5- A Driver file which matches your interface card. For RamFAST, it is Ramfast.Driver. For Apple SCSI cards it is SCSI.Manager and SCSICD.Driver. The Driver file(s) should be in the SYSTEM/DRIVERS/ folder (i.e. the DRIVERS folder in the SYSTEM folder).
From the Apple Menu click on Media Controller to show the CD ROM player. Click Channel 1, the name of your CD ROM driver sould show in the player display. Insert a CD. Click Play and adjust the volume on the drive. Loading Data, Games, etc. from a Data CD Startup is the same as described above. It seems to be a good idea to have a data CD in the drive before turning ON the computer. Some drive + card combinations may not go on-line if no CD is present by the time you turn ON the computer.
"Fine; but, how do I ask the Family Doctor a question, peruse an encyclopedia, and use other neat CD-ROM data disc products?" Actually, with HS.FST in your SYSTEM/FSTs folder, you can click the CD- ROM icon, display folders, and even load TEXT files from discPassage CD's. Your IIgs is 'compatible enough' with ISO 9660 even if some of the PC filetypes are unfamiliar. Still, this kind of access is hardly satisfactory. What you lack is the software key to unlock the discPassage database.
If you already have CD-ROM up and running on your IIgs, then hard disk installation of discQuest should involve nothing more than creating a folder named DISCQUEST, copying the program there and copying CoPilot.8 to SYSTEM/FONTS. The other files were present in Sequential's Complete System Package. The one sent to me included discQuest software and info sheets, NEC MultiSpin (x2 speed) CD-ROM reader, RamFAST SCSI interface card, cable, Labtec CS-150 amplified speakers, manuals, and four more sample CD's.
created other folders (Games, Graphics, etc.). All in all, 100+ floppies and a 340 meg hard drive had been turned into a nice, organized 105 meg archive. After double checking the archive, I slapped a blank CD into the recorder, started EZ-CD Pro, and selected "New" from the file menu. I scanned the displayed listing of burn formats for "HFS" because it is recognized by both GS System 6 and Mac. Unfortunately, HFS was not in EZ-CD Pro's list; so, I selected ISO-9660, which System 6 can handle via the HS.
I made a ProDOS 8 CD-ROM just today for the first time. I used Windows '95 since it has APSI driver emulation in an MS-DOS prompt and a *freeware* utility called DISK2CD from http://www.goldenhawk.com . It consisted of only these few steps: 1. 2. 3. 4. 5. Get all software onto youir Apple II hard drive that you want written to CD. Disconnect the hard drive. Reconnect the hard drive to a Windows '95 or DOS machine with appropriate ASPI drivers. Run DISK2CD.

033034035036037038039040041- How can I set default volume and folder under ProDOS? How can I discover the volume name of a just booted disk? How do I create a folder? How can I access ProDOS routines from machine language? How can I convert DOS 3.3 wares to run under ProDOS? How can I modify ProDOS to do BLOADs to Text Page 1? How can I boot ProDOS on my Franklin computer? What are some good DOS 3.
lets you use the semi-colon as a terminating 'wildcard' character. This DOS includes a CATALOG fix to show correct size of files bigger than 255 sectors. Other popular, higher speed versions of DOS 3.3 include David DOS and Diversi-DOS; and, there are several small, special-purpose versions of DOS 3.3. (For example, one game maker used RDOS to save space and to make its diskettes harder to copy.) Below is a chart which compares speed and features for standard and speeded versions of DOS 3.3.
BSAVE NARF, A$300, L$7F - saves $7F bytes of memory starting at address $300 as a binary file named NARF. (BSAVE NARF, A768, L127 uses decimal numbers to do the same thing.) note: The above command statement illustrates typical DOS syntax ...
IN# 0 - sets the source for Apple inputs to the keyboard (default). INT - (integer) puts system into Integer BASIC if it is present. FP - (floating point) puts system into standard Applesoft BASIC. OPEN NARFOO - prepares to read or write a TEXT file named NARFOO. READ NARFOO - tells DOS that INPUT and GET statements will obtain characters from a TEXT file named NARFOO. WRITE NARFOO - tells DOS that PRINTed characters will go to a TEXT file named NARFOO.
______________________________ 007- How do I create new DOS 3.3 diskettes? One of the best features of DOS 3.3 is that any bootable DOS diskette can create other bootable diskettes. INIT HELLO - formats one side of the diskette in the currently active drive, adds DOS, and saves the current program as HELLO. The program that's automatically placed on the new diskette is the one in memory when INIT is executed.
Yes. DOS 3.3 does not have a plain "FORMAT" command; but, you can use utilities such as Copy II+ to easily format a diskette without adding DOS or a HELLO program. A format will create 35 Tracks of 16 256-byte sectors each and verify that each Track is good. Then, it will allocate the Catalog track and create a disk info record called the "Volume Table of Contents" or "VTOC".
______________________________ 012- What does it mean to "Boot" a disk? BOOT comes from the idea of 'pulling yourself up by your bootstraps'. The Apple II disk controller ROM has just enough smarts to load-in DOS's Bootstrap Loader from Track 0, Sector 0 (it comes in at address $800 ...). The Loader loads in a still smarter, bigger routine from several sectors of Track 0.
the source files appeared in the catalog as "L" if you booted LISA, or "B" if you booted a normal disk. The "B", "A", "R" and "S" special file types cannot be accessed by BASIC programs (unless you patch DOS) - commands are only provided for dealing with "B", "A", "I" and "T" files. The four special types can only be accessed using direct calls to the File Manager. ______________________________ From: Dave Althoff, Jr. 014- What do the entries in a DOS 3.3 Catalog display mean? A standard DOS 3.
DOS 3.3 works like this: JSR $3E3 ;get address of RWTS IOB (low in Y, high in A) (you can either change the stuff that Y/A point to, or set up your own IOB and skip the call to $3E3) JSR $3D9 ;call RWTS (with IOB address in Y/A) The IOB (Input/Output Block) is small but non-trivial.
According to The Dostalk Scrapbook, there are 3 official (as in Apple made 'em, I think) versions of DOS 3.3. PEEK (46725) supposedly tells you which is running: 165: oldest 186: better 182: latest (1980) (January 1, 1983) (?) I remember one had something to do with the way text files are handled. ______________________________ From: Dave Althoff The second version would be the IIe release ("DOS 3.
______________________________ From: Neil Parker and Rubywand 019- What information is included in the DOS 3.3 VTOC and catalog sectors? VTOC The Volume Table of Contents (VTOC) is Sector $00 (0) on Track $11 (17). This is the key sector from which all searches start out. Example: A typical DOS 3.3 Disk's VTOC sector Byte 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0000001000200030.... 0080....
$3C-3F Bit map for Track $01 .... $80-81 Bit map for Track $12 (18) Example: The entry shown is 3F 7F 00 00. Only the first two bytes (3F 7F) are used: SectorBitHex- F E D C 0 0 1 1 3 B A 9 8 1 1 1 1 F 7 6 5 4 0 1 1 1 7 3 2 1 0 1 1 1 1 F This shows that on Track $12 only sectors $F, $E, and $7 (15, 14, and 7) are used. The other sectors on the track are free for use. ....
______________________________ 020- How does DOS 3.3 remember which sectors are used to store a file? Every file has a set of one or more Track/Sector List sectors. A Track/Sector List (T/S List) lists sectors (by Track and Sector number) which make up the file. Each T/S List sector points to up to 122 data sectors If the file is too long for one T/S List sector, a second one is allocated, and a pointer to it is stored in the first one, and so on. Note that DOS 3.3 supports "sparse" files...
position which is a multiple of the random-access record length. (Note that sequential and random-access text files share the same file type. It is up to individual programs to know whether their data files are sequential or randomaccess.
______________________________ From: Rubywand 022- How can I run DOS 3.3 programs from 3.5" disks and hard disk? You can run quite a few DOS 3.3 programs from 3.5" disk, a large RAM disk, or hard disk. However, there are numerous DOS 3.3 programs which will not run this way and which could even damage files and directories on the larger media.
>> If you have properly installed DOS 3.3 Launcher, your DOS 3.3 programs should appear with DOS 3.3 icons when viewed through the Finder. To launch them, you simply double click on them, which launches them via ProDOS 8. << Of the two basic approaches (a special 3.5" DOS 3.3 or DOS 3.3 Launcher), DOS 3.3 Launcher seems to be the better way to go: First, it is easy to set up the contents of a DOS 3.
provides much faster disk I/O than standard DOS 3.3. ProDOS is a whole new disk operating system. To get ProDOS from the net, see Csa21MAIN4: Get It- Links to popular software packages. ______________________________ 025- What are ProDOS's major features? ProDOS has lots of nice features-- mainly, you can create sub- directories, diskettes ("volumes") can be named, and ProDOS works well on hard disks. The GS System 6 Finder can handle ProDOS files and launch programs from ProDOS diskettes.
Another way is to use Disk Muncher or some other whole-disk copier to copy some bootable ProDOS diskette which includes BASIC.SYSTEM. You can delete any files you don't want from the copy. Things are a bit easier on a IIgs running GS System. In the Finder (the usual GS main 'desktop'), you can insert a blank diskette and let Finder "Initialize" it for ProDOS. Then you can mouse 'drag and drop' PRODOS and BASIC.SYSTEM from a bootable ProDOS disk to your new disk.
______________________________ From: Rubywand 030- How do I LOAD, SAVE, etc. files under ProDOS? LOAD (SAVE, RENAME, etc.) work very much as in DOS 3.3.; so, you can use Slot and Drive parms to specify the target volume. However, to get the most from ProDOS you will usually be working with volume names and folders. (or, "directories"). If GAME3.PIC is a binary file in a directory named "PICS" on a volume named "NARF", you could load it into memory starting at address $2000 via BLOAD /NARF/PICS/GAME3.
______________________________ From: Rubywand and David Empson 032- What is the default volume and folder (directory) when ProDOS boots? When ProDOS boots, it will assume that LOADs, SAVEs, etc. refer to the main directory of whatever volume is in the boot Slot and Drive. It does not automatically establish a default volume or folder by name. So long as no default volume name is set, references to disks by Slot and/or Drive (e.g.
that folder without worrying about the names of the volume and folder in which your Eamon stuff is located. If you know that the EAMON folder is in the currently active directory, you can use PREFIX EAMON/ or, in a BASIC program 100 PRINT CHR$(4)"PREFIX EAMON/" to set the folder as the default location without having to specify volume name. If the current default is /NARF/, the command will result in the new default being /NARF/EAMON/.
o- If there is no established default prefix, then, ProDOS will read the volume name of the volume in the default Slot and Drive. Note: PREFIX used in this way does not establish or change a pathname prefix. Booting clears any default prefix and sets default Slot/Drive to the boot drive. For your STARTUP program to discover the name of the volume on which it resides, it could execute the following: 100 PRINT CHR$(4)"PREFIX": INPUT"";P$ The volume name of the just booted disk (e.g.
For a detailed description of functions including command codes and parameters, see a ProDOS manual or one of the other references mentioned in Q&A 040 below. ______________________________ From: Rubywand 037- How can I convert DOS 3.3 wares to run under ProDOS? Quite a few DOS 3.3 programs will run fine under ProDOS with no change at all. Unless you have some reason to believe a DOS 3.3 program will not run under ProDOS, it's worthwhile to just copy it to a ProDOS diskette and give it a try.
EXEC the resulting Text file, you can obtain an Applesoft BASIC program which you can modify as necessary for ProDOS. 6. It's not DOS 3.3: Very old software, old commercial copy-protected software, and deprotected copies of old software may not be on DOS 3.3 disks. Your first challenge with such software is getting it into a form which will permit transferring files to a ProDOS diskette. When checking and modifying a DOS 3.3 program for ProDOS a good program editor is essential.

specific application, it is best to stick with 35 tracks in order to retain full compatibility with disk utilities (such as Copy II Plus) and other wares. ______________________________ 002- Can I use high-density 3.5" and 5.25" diskettes on my Apple II? I did some magnetization tests on Double Density (800kB) and High Density (1.4MB) diskette surfaces. The tested DD surface produced more than twice the deflection of the tested HD surface.
______________________________ From: Rubywand 004- Recently I found that some of my old 5.25" disks would not boot. A check showed splotches etched on the surface of the media. What's going on? As you may recall, a number of the classier 5.25" diskette brands employed (still employ?) a lubricant on their jacket liners.
You can, still, run software from most copy-protected diskettes by just booting them. ______________________________ From: Vincent Joguin, Charlie, Rubywand 007- Can I read Apple II diskettes on my PC? Yes. There is a way for some PCs to read Apple II DOS 3.3 and ProDOS 5.25" floppies which are not copy-protected. By "some PCs" I mean that the PC must have two floppy drives (only one has to be a 5.25" drive) and it must be running MS-DOS or Windows 95, 98, or ME. (It won't work with NT, 2000, and XP).
The other common way of moving the data is to connect an Apple II to a PC using a NULL modem cable and using comm programs such as Kermit to transfer the data. ______________________________ Michael Hoffberg About a year ago, I picked up card for my ibm made by TrackStar. It is basically an apple II that sits inside your IBM. When you enable it, it can boot off an apple drive, it uses the ibm keyboard and monitor.

as the ones included in Copy II Plus, Locksmith, and Essential Data Duplicator, may get the job done. Using it's built-in parms library, Copy II Plus can reliably make copies of many copy protected disks. If a lot of the software you need to copy is from MECC, a good try is to get an MECC copy program by John Kielkopf named "meccopy". It makes deprotected copies of many MECC diskettes.
There was a thread discussing the impossibility of creating bootable ProDOS disks from a Mac with a 'force-feed' floppy drive. Seems it ain't necessarily so. Using Bernie ][ the Rescue on a G3 iMac with a cheap USB floppy, I first create a Diskcopy 4.2 800KB image, which I copy to a 1.44 MB diskette with the finder. Then I transfer the disk image to a PowerPC 6100/66 which has the non-autoinject disk drive (running System 7.5)... copy the image to the HD.

This has happend to me when Dragging files around. I recommend you recopy the game from your original disk, or re-unShrinkIt to the location you wish it be.
A $0201 error when switching to ProDOS-8 usually means some utility has left part of bank 0 or bank 1 allocated.

1301 "Unknown error $1301"- When I tried to open a file in Platinum Paint, I got this error message. What's wrong? I got the same error message when I tried to run Platinum Paint with Bernie ][ The Rescue on a G3 Power Mac. The error code refers to a missing driver; but, even if the correct printer driver is present, what Platinum Paint really wants is for the D C Printer Control Panel settings to be correct.
with no problem. However, when I attempted to partition it, I saw the error message listed above. As it turns out, this drive has a place for a jumper documented to "Disable TI Negotiation." Before giving up all hope, I put a jumper in there.

Control Panel, especially for a SCSI interface, it may be necessary to turn Off the computer and do a fresh power-up for the new setting to be in effect. If the expectation is to boot from /RAM5 RAM disk, make sure that /RAM5 is initialized before copying files to it. (/RAM5 is normally automatically formatted as a ProDOS volume when you first power up; but, it will not have the required boot block unless it is initialized or unless you do a whole-disk copy to /RAM5 of a bootable disk.

From: Stephen Buggie 001- How do I add a write-protect On-Off switch to my Disk ][ drive? Adding an Auto/Manual Write-Protect (A/MWP) Switch Often, as when doing copying, it is useful to be able to guarantee that a diskette is Write-Protected whether or not the side is notched. Other times, it is convenient to defeat Write Protection-- for example, when you wish to write to a diskette side which is not notched. And, naturally, you also want a setting which permits Normal, notch-controlled, Write-Protect.
Cut the Notch Detect micro-switch leads about 1" away from the Large Connector. Connect the Black Notch Detect, Black Large Connector, and Black Switch leads (i.e. strip ends, solder, and cover in heat-shrink tubing or tape). Connect the Brown Notch Detect lead to the White Switch lead. Connect the Brown Large Connector lead to the Brown Switch lead. Viola! Now you're ready to replace the cover, plug in the drive, and try out your A/MWP enhanced Disk ][.
______________________________ From: Stephen Buggie 002- How do I add an external speed adjustment to my Disk ][? Reference: FAQs Resource file R006SPDKNOB.GIF Adding a Speed Control Knob to your Disk ][ Drive This article tells how to move speed adjustment from the Disk ]['s dark interior to a handy front-panel location and how to "tune" the drive for optimal performance.
6. Re-mount the daughter board. Mount the 5k Ohm pot. Install knob. 7. Bring the drive back to the computer. Slide it onto the case bottom plate, reconnect main ribbon cable, replace bottom bolts, slide on and re-fasten case top. You can use Copy II Plus, XPS, APEX, or one of several other utilities to set speed (see next question). A good starting adjustment will be near the center of Speed Knob's range.
pinch, a diskette formatted by any drive that has no problem reading most other diskettes should be okay.) Basically, a track-centering test tries to step your head between two tracks of the 'standard' diskette and read the tracks on either side. If the number of successful reads from each track is about equal, the head is "centered" and your drive is well-aligned with the standard diskette. The test may indicate serious misalignment.
The 3.5" diskette has a small plastic panel you can snap out for cleaning two-head drives. Since the standard 3.5" 800k Apple II drive has two heads, snap out the panel so that both the top and bottom heads get wiped. To clean your drive head(s), you sqirt a few drops of Cleaning Fluid onto the Cleaner Diskette disk, insert it into the drive, and get the disk spinning. Allow about 20 seconds for a 5.25" and a couple10-second spins, with drops between spins, for a 3.5" drive.

The following is excerpted from an info file from my old bbs ... There are TWO modifications that should be made to Duodisk drives: The First one was recommended by Apple several ago to solve occasional problems with trashing diskettes. The solution is to remove 2 capacitors.
Remove the top cover and turn the drive so that the identifying number will be at the bottom left of the analog board. The number might read 676-[]101, 676[]102 or 676-[]107. (ROM 3 GS users should check Q&A 007.) If the I.D.# for the analog board is 676-[]101 or 676-[]102, use a pair of nippers and cut out resistor R8 (located at position A2). If the I.D.# for the analog board is 676-[]107, use a pair of nippers and cut out resistor R39 (located at position C3).
______________________________ From: John L. Graham 008- How do I fix a false Write Protect? I recently ran into this problem with a Disk II. It insisted the disk was write protected. I checked the write protect switch, but it was okay. I pulled all the chips out of the analog board inside the drive, cleaned the contacts with a clean pencil eraser (one was _really_ dirty, almost looked burnt) and reinstalled them. Voila! The problem went away. ______________________________ From: Rubywand 009- My 800K, 3.
A 3.5" drive that, after cleaning, cannot boot known-good diskettes is likely to have screwed-up heads. However, it's a good idea to try unplugging and re-plugging the drive (with the computer OFF) and, then, try another boot. If you have a 5.25" drive attached, boot ProDOS from the 5.25" drive and try some CAT's of non-protected known good 3.5" diskettes in the 3.5" drive. As earlier, do the cable wiggling test while attempting the CAT's. A very good test is to try out the drive on a friend's IIgs or IIc+.
1. The 74LS132 on the Disk ][ Controller card may have a blown gate or some pins may be making poor or no contact. Try unplugging and re-socketing the IC. This usually takes care of bad contact problems. (Or, you can replace the 74LS132 IC with another 74LS132 or 74132. A 74LS00 or 7400 may work, too.) Also unplug and re-socket the 9334 and 556. 2. The ULN2003 IC on the Drive 2 main circuit board may have a bad gate or may have developed some poor pin-to-socket contacts. Remove the drive cover.
______________________________ From: Rubywand 013- Last night a sound like a shotgun going off came from my 5.25" Disk ][ drive. Now it doesn't work. How can I fix it? The noise was probably an electrolytic capacitor exploding. Sometimes, these develop internal shorts, heat up, and blow (kind of like a sealed can of beans on a campfire). The fix is to remove the drive cover and replace the blown capacitor. (Look for a small can-like component with goo and/or shredded foil coming from it.

forward. The early version of the external Mac mechanism is mounted in a plastic casing that resembles the Apple II platinum drive except that the manual eject button is absent. Remove the mechanism from the casing, but save its round external cable and db-19 plug --- that cable/plug can be used later to adapt flat-ribbon Apple II drives for use with the IIgs or IIIc! The Mac externaldrive's plastic casing can be saved for use as a coin bank, or discarded.
With the black and red plugs each removed, slide the top plastic cover in a rear-to-front direction, past the metal-enshrouded mechanism. The wire-pairs from the eject-button and also from the in-use LED lamp should remain tucked into their plastic side-braces. You now hold the mechanism, enshrouded in its grey metal shielding, with the external db-19 cable protruding from the rear. Remove the two medium Phillips mounting bolts (with flat washers) from each side.
casing and the metal shroud. Insert the black and red plugs into their respective connectors. Note the "R" and "B" markings you wrote on the metal shroud; those markings will guide the plugs' in sertion into their proper connectors. The oblong-shaped grommet attached to the round external cable should be fitted first to the bottom plastic half-shell casing, which is then mated to the top casing.
But the sticker is hardly a reliable test. A better test is to look look at the part numbers of the P5 PROM (the lower left chip on the card) and the P6 PROM (left column, second from the top). P5 P6 13-sector --------341-0009-xx 341-0010-xx 16-sector --------341-0027-xx 341-0028-xx The 16-sector PROMs may also be labelled "P5A" and "P6A". A program can test the card type by looking at its slot ROM space.
______________________________ From: Rubywand 019- I would like to add a Read/Write indicator to my Disk ][ drive. How can I do this with a bi-color LED? The circuit described below works well. It shows Red for Drive Enabled + Write and Green for Drive Enabled + not Write. That is, a Read is assumed if the drive is ON and no Write is occurring. The advantage of this approach is that you always have a lighted LED 'drive ON' indicator and, so, there is no need to drill a new hole in your drive panel.
Old "in Use" LED- pop off the retainer ring and push through the LED. Leave the LED mount in the hole. Cut off the LED, spread cable ends and tab over with cellophane tape. (Put old LED and ring into parts box. Spread apart retainer 'leaves' of LED mount (at back side of panel) to permit easier insertion of new 3-lead LED. Run LED + cable over back of board and along bottom toward the hole in the front panel. Push through hole.
recognize HD disks just fine. You can even boot off of a HD disk, allowing plenty of room for System Desk Accessories and such. There are a few drawbacks: You cannot boot copy-protected software or some FTA demos. You can't daisy-chain a 5.25" on an HD card. Also, it takes up a slot, even on the GS. ______________________________ From: Benjamin Summers 021- What is a "UniDisk"? The UniDisk 5.25 was Apple's replacement for the venerable Disk ][.
o- Set "Minimum RAM Disk Size" and "Maximum RAM Disk Size" to the the same value = size of the RAM disk you want. If you have enough RAM left over to start your operating system and run your favorite application, a good RAM disk size is 800k. o- Press Return to set the value. Exit the Control Panel. Exit the Desk Accessories menu. Turn OFF the computer. When you next power up your computer, your RAM disk will be ready to use. ______________________________ From: David Empson 023- Which 3.
For the RAM disk to be bootable, you need to do a whole-disk copy of a same-size bootable diskette to the RAM disk. Or, you can initialize* the RAM disk before you copy files to it or do an install. *Note: To initialize the RAM disk, click on the RAM disk icon to select it. Then, click on "Disk" on the menu bar and select "Initialize". Follow the prompts to init the disk. Finally, in the IIgs Control Panel, go to Slots and set Startup Slot to "RAM Disk".

Today, practically all servers can handle pure binary transfers; so, binscii is no longer in popular use. However, quite a few old A2 files are still in binscii form and binscii is used for files uploaded to comp.binaries.apple2. To convert binscii'd files to their un-biniscii'd form, you can use a program named "BINSCII" or, on a GS, the New Desk Accessory named "GScii". These programs can, also, create binscii files. Note: Binscii is in no way related to Binary II.
files of old 5.25" wares. (Balloon does not currently support whole-disk archives.) Naturally, things are somewhat more crowded on 64K Apple II's. On these machines, the functions are separated. SHRINK creates .SHK files and UNSHRINK unshrinks them. On a PC, the utility NuLib (v3.24) lets you view contents and unshrink most kinds of .SHK files. (There is a handy option to unshrink and convert Apple II text files to PC text format.) It will not unshrink IIgs files with resource forks.
Several utilities can change ProDOS filetype. If you do not have one, you can download tchange.bin and follow the directions* in tchange_info.txt to get it going on your Apple II. You can find GS-ShrinkIt in an .SEA file (e.g. gshk.sea) and tchange.bin on several archive sites. (See Q&A 007 below.) B. The Shrinked Disk (.sdk) version GSUTILS.sdk is a shrinked whole-disk file which can be unshrinked to 800k 3.5" diskette using 8-bit ShrinkIt (or GS-ShrinkIt).
PREFIX /HD1 o- Now, enter -SHRINK.EXE (that's a dash, then the file name): -SHRINK.EXE Shrinkit will self-extract, along with a documentation file. (ShrinkIt v3.4 consists of two files. One is a small start file which may be named "Shrinkit.System", "ShrinkitST.sys", or something similar. The other is the main program file which must be named "Shrinkit".) You can find SHRINK.EXE in Ground's useful.stuff/ folder (See Q&A 007 below).
______________________________ From: Rubywand, Orgone Accumulator, Greg E. Nelson, Eric Shepherd, Roger Johnstone 006- What are DSK, PO, DO, HDV, NIB, and 2MG "disk image" files and how do I use them? A "disk image" is typically a file containing every data byte on a diskette-- i.e. Catalog tracks, files, DOS (if present) etc.. One kind of disk image, NIB, tries to preserve all disk information (e.g. sector headers, sync bytes, etc.). Apple II emulators running on a PC, Mac, etc.
On a PC, NuLib can create disk images from 8-bit ShrinkIt whole-disk (.sdk) files (but not from .sdk files which were produced by GS-ShrinkIt). These images will be in ProDOS order. You can convert a .po disk image to a DOS 3.3 order .dsk by using a disk copier like Disk Muncher on an emulator to copy from the .po image to a .dsk image. On ftp sites, DSK files are usually in a ZIPped form to conserve space. For example, on the Asimov site, narfgames.dsk.
7. Select the "Image file ---> Diskette" option, follow prompts, and you should end up with a good diskette. (If everything seemed to go well but the disk does not work, try repeating the process using the other "Order" option.) DSK2FILE and ASIMOV can, also, create disk image (.dsk or .po) files. Similarly, using ADT to transfer a 5.25" disk automatically creates a .dsk disk image on the PC. The source disk can be for a game, etc. so long as the diskette is not copy protected. Note: DOS 3.
You can use ASIMOV2 to convert .2MG files back to diskette form as well as for creating .2MG files from 800k diskettes. The utility Imgutnew.exe can be used to convert most available Diskcopy images to 2MG format on PC. *See ... Size Note: Transferring to 3.
If you download a GZ file directly to your Apple you can use a program named "GZPK" v2 to convert it from gzip form to a zip format which can be unzipped via PMPUnzip 2.0 or Angel. A GZ file from the Asimov site should end up as a DSK file. ______________________________ From: lachlan_arnott and Byron Desnoyers Winmill On a Mac, you can use uncompressed form. Another Aladdin's StuffIt Expander be found on many Macintosh MacGzip to unZIP g-zipped (.
I also prefer File-A-Trix. It performs a wide variety of functions including copy, move, delete, rename, catalog, make new folder, set file attributes (lock, unlock, filetype, auxtype), find file, format (floppy only), view text, Teach and AWP files. Best of all, it's a CDA that works from GS/OS and ProDOS 8, although there are some restrictions under P8 (i.e. no HFS disk access, no viewing forked Teach files, etc.) ______________________________ From: Gareth Jones I use either File-A-Trix, Change-A-File 4.
______________________________ From: Rubywand 010- What is Copy II Plus and where can I get it? Copy II Plus is the best general purpose utility for copying disks and managing files on DOS 3.3 and ProDOS diskettes. Most of the Copy II Plus functions also work with disk images (e.g. .dsk files) on emulators; however, COPY DISK and FORMAT are important functions which do not work correctly with emulators. Good versions which handle both DOS 3.3 and ProDOS files are 7.x 8.x. Note: Versions 9.
are Copy II Plus disk image files. I have seen ".img" (and ".image") used for Diskcopy disk image files. ______________________________ From: Rubywand 012- I'm using an Apple II emulator to play games. The game directions say the boot disk must have a write protect tab. How do I set write protection for a disk image? Under Windows on a PC, you can right-click on the file name, select Properties, and adjust the "Read-only" attribute.
C:\WINDOWS>cd\ C:\>cd nulib o- Enter the xd command to create the disk image from modem1.sdk: C:\nulib>nulib xd modem1.sdk You should get a message saying the 'NEW DISK' image is being extracted ending with "...done". o- Exit the MS-DOS window-- e.g. click on the "X" in the corner. o- Open the C:\nulib folder. Probably, your new disk image will be named "new.dis". Rename the new file to "modem1.po". It should show up with a size of 140k in the usual Windows listing.
______________________________ From: David Kopper, Dan DeMaggio, Boris Guenter, Nathan Mates, Phil Abro, Rubywand, Labelas Enoreth, Tony Turner 015- What do the different popular file name extensions, like ".BSC", mean; and, how do I access the files? File name extensions tell you what sort of file you are dealing with so that you will know which program(s) to use to unpack, unShrink, display, etc. the file.
.GZ GZip PC archive format often used for storing A2 emulator disk images (GS GZPK v2 plus PMPUnZIP or Angel; PC WinZIP) .HDV Raw (DSK) ProDOS ordered disk image file 800K or greater in size; used by emus as a virtual hard disk (ASIMOV2 on IIgs) .HQX Mac BinHex file. [TEXT] (BinHex on Mac or GScii) .HTM HTML [TEXT] with embedded Text commands (Web browsers, web editors, etc.) .IMAGE Diskcopy images (see .DIMG) .IMG Type IMG or "user #7" Copy II Plus disk image file (A2 Copy II Plus v6.x or v7.x) .
Most files are in one of a few common formats, and many are a combination. .sit .hqx .bin .image .txt .bsc .shk StuffIt 1.5.1 archives BinHex 4.0 file Binary file Diskcopy 4.2 image file plain ASCII text file Apple II BinSCII file Apple II ShrinkIt file Most of the Macintosh files are BinHexed StuffIt files. This means you need to transfer the file, then read the license agreement which is prepended to it (with any text processor), use BinHex or any utility which can read BinHex 4.
then you've got something encoded by BinSCII. You must decode _all_ the parts using BinSCII. Then, if the resulting file is in some compressed form, you would use an appropriate utility to uncompress it. (For example, you would use 8-bit ShrinkIt to uncompress a whole-disk .sdk archive file.) On the other hand, if you have a binary file which resembles: NuFilei][![/#NuFX_<:c[[[ H`F-fGSCII~[ cRJ0)fNN^P)3'A2p6SF6X#GPd<9#'LC^08N7n\NB7Dd!eMN&eYX0Am=fXp dsPAsp7rh`I'NS0ALAfi2)2ysGEQ$k9CP%L9 ...
______________________________ From: Rubywand 017- How can I create 'blank' .dsk, .nib, etc. disk images? The simplest way to get a new .dsk or .nib is to copy an existing one and delete the files. Under Windows, you can just Right-click drag-and-drop a file in the same folder to get a copy. If you want a DOS 3.3 formatted image, pick a DOS 3.3 image to copy. If you want a ProDOS formatted image, pick a ProDOS image to copy. You can use a utility like Copy II Plus v7.4 to delete the files.
______________________________ 019- How can I convert Diskcopy images to diskette or to other formats? Diskcopy is a Mac disk image format with names ending in ".dimg", ".img", ".image", or with no suffix. (Sometimes, incorrectly, ".dsk" is used.) The typical length of a Diskcopy file used for an Apple II 800k image is 838,484 bytes*. On a Mac, you can use the Mac Diskcopy utility to convert diskettes to images or images to diskettes.
Although 2MG, Diskcopy, and some other 800k image formats greater than 800k, on a ProDOS diskette they will often occupy space. You will often be able to transfer such files (e.g. via connection) to an Apple II 800k diskette so long as you employ does not pre-send size information, such as X-modem.

Another interesting tidbit: remember Threshold? It was THE COOLEST Space Invaders clone ever to grace an Apple // screen (actually it was more of an Astro-Blaster clone). It was created by Warren Schwader (he also did that Cribbage game that had a bad bug in it.) Well, back in March 1992, we of id Software travelled to Sierra (Online) to show them a pre-alpha version of Wolfenstein 3D.
Well, I haven't heard about what Dan's been up to nowadays, but.....another one of Broderbund's previous blockbuster programmers HAS been busting his hump for a while on the NUMBER 2 RPG game of 1995 (voted by GamePro magazine)!

______________________________ From: Bradley P. Von Haden 001- How difficult is it to add a hard drive to my IIGS? Adding a hard drive is not much of a problem. Usually, you will need to insert an interface card, possibly connect a cable or two, and change a Slot setting in the Control Panel Desk Accessory.
- dual 50 pin SCSI connectors - no or switchable termination (use an external terminator at end of SCSI chain) - switchable termination power (on/off) is a plus for users of SCSI interface cards which do not supply termination power ______________________________ From: Rubywand Another way to go is a 2.5" IDE drive mounted on an IDE interface card. This "hard card" plugs into a Slot-- usually Slot 7. Alltech sells the Focus Hard Card in varying sizes (e.g. 60MB for $99) with system software installed.
There is no problem using SCSI ID 0 on an Apple II. On a RamFAST SCSI card, it is also safe to use SCSI ID 7 for a drive. The RamFAST doesn't have a SCSI ID, but every other SCSI card does. ______________________________ From: David Empson 004- What is "SCSI-2" and how is it different from SCSI1? For hard drives, "SCSI-2" basically means that the drive supports a stricter command set. The physical interface is usually identical.
used with a RamFAST SCSI card. A notable example is the Quantum Fireball series. However; the Trailblazer and all older Quantum models work fine. ______________________________ 006- I have a plain ol' Rev. C SCSI Card, will this work with a SCSI-2 drive? My Quantum LPS240 is working fine on an original Apple SCSI card.
______________________________ From: LJSilicon 008- I just reinstalled System 6.0.1. Now every time I cold boot I get this message 'RamFAST/SCSI is searching the SCSI bus for devices' and have to wait several seconds. WEIRD?! When you reinstalled the software, the RamFAST set itself for a long search. This is an option that you can change using the RamFAST utility. What it is doing is giving your scsi devices a chance to spin up.

Note: the numbers for the 50-pin connector are counted along each row, like a Dsub-25. They are NOT the wire numbers in a ribbon cable. ______________________________ From: Steve Reeves 010- Is there some patch for SCSIHD.
System 6.0.1 Three things I can think of to check: One possibility is DMA compatibility. If your memory card is not DMA compatible, then switch 1 on the Apple HS SCSI card should be open (up). Another possibility I guess is a SCSI ID conflict. The Apple HS SCSI card's ID at the factory is set to 7.

(Yes/No)', middle 6 not used, last (right) is 'multiple initiators (Yes/No)'...manual shows no jumpers in default configuration u 3: Selection phase time out delay....I believe this sets how long the card waits for the drive to come up to speed(?)...
The 1987 ROM uses jumpers on the card to define the partitions on the drive. These partitions cannot be greater than 32MB and only two partitions are supported. The manual should be considered a MUST HAVE. The 1989 ROM is similar to the 1987 ROM in functionality, but it has an annoying habit of shutting down the drive after a period of inactivity. It needs an access attempt to start it up again, but this access will return a failure error code (ok when you can redo the action but not too good otherwise :).
Switch on the hard disk, wait about 10 seconds for it to come up to speed, and then restart the computer." From the Macintosh User's Guide for desktop Macs, page 216: "IMPORTANT: Always turn on any external SCSI devices connected to your Macintosh before turning on the computer itself. Otherwise, your computer cannot recognize the SCSI devices.
The Termination Power modification for Apple SCSI cards consists of adding a diode. The mod for each card is shown in resource file R009SCSIMOD.GIF. The High-Speed card pic shows a simple sketch of the back of the Apple High Speed SCSI card near connectors 26-33. The directions say that you connect a 1N914 diode between two points: The anode (non-banded end) of the diode goes to the *top* of L1.
______________________________ From: Scott G 021- How is DMA set for SCSI cards with 8MB RAM cards on the GS? DMA needs to be turned off with the Apple HS SCSI card or the RamFAST revision C card. It does not need to be turned off with the RamFAST revision D card (differentiated by being half sized). Current RamFAST cards are revision D as are late model CV Tech cards. It is the RamFAST revision D that is designed to DMA into any RAM card, even 8MB models.
The Apple High Speed SCSI card has a printed label on one of the chips showing the name "Sandwich II" on it. ______________________________ From: David Empson The ROMs for the three (non "High Speed) Apple SCSI card firmware revisions are ...

______________________________ From: Paul Guertin 001- Could anyone suggest a good project book for the Apple IIe. I'm interested in using an old box for tracking the temperature in a water bath. Vernier software publishes a book called "How to Build a Better Mousetrap" which contains 14 hardware projects for the Apple II. Project #6 is a temperature probe connected to PDL0. ISBN for the book is 0-918731-16-X. Vernier Software ( http://www.vernier.com ) 2920 S.W.
the "count" as a function of the variable resistance. Then compare the plot against the resistance curves for the thermistor (probably not linear), and work out some conversion formula to use in your program to correlate "count" to temperature. ______________________________ From: David Empson 003- Can I use the same prototyping Slot Board for all of the different Apple II's with Slots? Prototyping boards certainly would be the same for the II, II+, IIe, and IIgs.
Pin 27: DMA daisy chain in. Pin 28: Interrupt daisy chain in. Pin 29: Non Maskable Interrupt. Pin 30: Interrupt Request. Pin 31: Reset. Pin 32: this is the INHIBIT pin on all machines. This behaves differently on all three machines: the II and II+ only allow the $D000-$FFFF ROM area to be inhibited. The IIe allows RAM to be inhibited as well, but has strange interaction with main and auxiliary memory. The IIgs only allows this signal to be used if the machine is running in slow mode. Pin 33: -12V.
______________________________ From: Rubywand, David Kopper, Guenther Unger, Gabriel Hawkins, Michael Mahon 005- I've been getting Fatal System Error 0911 and when I do the internal diagnostic it gives a system bad : 09010001. Is there a fix? Fatal System Error 0911 and Self-Diagnostic Test 09010001 mean the same thing: You are, very likely, experiencing one of the following malfunctions: o- Temperature-sensitive ADB IC This problem was first identified in a 1988 article in issue #58 of Computist.
The idea is to quickly warm up the IC. I used a scheme like this on our early GS and 0911 bombs dropped from 4-5 per day to 2-3 per week. If you can safely power the bulb via an external power module (e.g. a calculator or radio 'AC adapter') so that the bulb can be ON at least a few minutes before powering up the computer, 0911 bombs might disappear entirely. o- Defective keyboard, loose connector on KB, and/or a bad KB cable Some users report that swapping in another keyboard cured their '0911 crashes.
______________________________ From: Rubywand, Duncan Entwisle, Jerry Cline, Bruce Baker 007- How do I replace my GS "BatRAM battery"? The standard GS battery is a 3.6V Lithium type rated at 1.2AH. It is called the "BatRAM" battery because it keeps the Battery RAM and Clock IC going when you turn OFF power. To get to the battery, you must disconnect the AC cord and pop out the Power Supply. If you have a ROM 03 GS, you can slip out the old battery and slip in 'one like it'.
Especially if you are joining bare leads to bare leads, you could end up with more bare wire than you are comfortable with. Check that the bare leads do not touch anything they should not. Bend the leads as required and position the new battery so that nothing will bump into the Power Supply when it is replaced. The usual recommendation for this kind of work is that the computer be OFF. This reduces the risk of damage should a bit of solder, a wire, etc. fall onto the motherboard.
______________________________ From: George Rentovich 010- I'm afraid that oxidation on pins may be causing bad contacts and memory problems. How can I remove the oxidation without resorting to sand paper? Tarn-X works great for removing oxididation from chip pins without a lot of work or risk in harming the chips. Soak the chips in a shot glass until all black oxidation is gone; then, remove the chips and put them in another shot glass with alcohol to rinse.
so 15-20 turns of small wire-- like wirewrap wire-- wrapped on a pencil or screwdriver shaft will make a small coil you can use. Make three coils. After removing the damaged L2 module, use an Ohm meter to check for a short to ground at pins 1, 2, and 3. (If, as in the case of a short in a spliced-on KB cable, you know where the short is/was, you can skip this check.) Eliminate the short before continuing. Solder your home-brew coils in place (pin 1 to pin 8 for the first coil, etc.
For 512kB, the entire top row of sockets should be filled. The bottom pair of pins should be jumpered. XXXXXXXXXXXXXXXX ---------------O O 0-0 Jumper bottom pair For 1MB, all sockets should be filled. The top and bottom pairs of pins should be jumpered. XXXXXXXXXXXXXXXX XXXXXXXXXXXXXXXX O-O Jumper top and bottom pairs O-O To get the full IIgs mem card upgrade to 1MB you can order a kit of 24 256k x 1 41256 DRAM mem IC's from Alltech (760-724-2404) for $24.00.
______________________________ 015- I recently picked up a spare GS from a flea market and would like to convert it into a portable. Has anyone done this? Yes. Tony Diaz has an article describing a couple conversions on his web site at http://www.apple2.org/AppleIIgsPortables.html . ______________________________ From: Erick Wagner 016- Where can I get Robot kits to use with my Apple II? If you have a an RS-232 interface (2400 or 9600bps) you might consider a kit from Lynxmotion ( http://www.lynxmotion.
______________________________ From: Gilles Aurejac 018- What chip can I use to replace a bad RAM IC on my IIe motherboard? The 4164 (64k x 1) works on motherboards using eight memory chips. The RAM on my motherboard is in sockets; so, it was easy to replaced a bad memory chip with one.
______________________________ From: Mitchell Spector 020- What advantages does the ROM 3 GS offer vs. the ROM01 GS? The ROM 3 Apple IIgs offers many minor enhancements vs. the ROM-01 which make the machine more functional and pleasant to use: - You get a machine that is about 5-10% faster for GUI, floppy disk loading and RAM Disk operations (due to updated smartport firmware and System 5 tools being in ROM).
The down side is that some old GS games and demos won't run. However many of the more worthwhile ones have been patched. ______________________________ From: Scott G 021- How can my ROM 3 GS + 8MB Sirius card do large file copying? An error in the Sirius manual (a 1 page paper) recommends that ROM 3 users remove one of the SIMM modules since the ROM 3 has 1MB and 8MB is max. When I did this, the GS reported 8MB, but copying large groups of files or large files (>800k) failed.
______________________________ From: David Wilson 023- I have several different model Apple II computers ranging from a II+ up through a IIgs. Does anyone know where I can get diagrams for these machines? I know of three books with Apple ][+ schematics: Jim Sather's "Understanding the Apple ][" "The Apple II Circuit Description" by Winston D. Gayler published by Howard W. Sams & Co (ISBN 0-672-21959-X) Apple II Reference Manual (1979) ______________________________ From: Charles T.
______________________________ From: David Empson 024- I just got a Dallas Smartwatch (aka No Slot Clock) for my Apple IIc+. Where does it go? There is only one ROM in the IIc+: it is probably 32KB in capacity, like the UniDisk revision of the IIc and later IIc models, hence it would be a 28 pin chip. Assuming the SmartWatch works in the IIc+ (and I don't know of any reason why it wouldn't), you need to put it under the chip labelled "Monitor ROM".
board, you will probably have to get a PC ISA-8 ("PC XT") Slot board (or an ISA8/16 Slot board with the extra contacts trimmed off). An ISA-8 board has 31 contacts per side spaced the same as an A2 card. From the edge facing the front of the computer, you will need to count down and trim away 6 contacts (per side). It's best to use a real A2 board as a guide to determine pin centering and to decide what to slice off for a good fit in an Apple II Slot.

Years of exposure to sunlight and other UV can result in yellowing or even browning of Apple II cases. One solution is to pick a color and paint the case via a few light coats of a spray paint. If you want to restore the original color, you can get a good match using Apple II pictures available on the net. A recently discovered alternative to painting is bleaching out the discoloration using hydrogen peroxide (H2O2).
Note: Sometimes H2O2 concentration is expressed in "volume". A peroxide product for hair bleaching may be labeled "40 Volume". To get the % concentration, you divide by 3.3. 40 Volume = about 12% H2O2. H2O2 specified as "not less than 20% nor more than 40%" is available in a gallon size as a cleaning product called "Urine Rescue" by Prochem for about $15/gallon. You can obtain 12% H2O2 (such as "Super Star 40 Volume Clear Peroxide Gallon" for $7.77/gallon) from various hair salon sellers.
The UV light to be used for indoor work is 'blacklight' UV. It is sometimes used to highlight posters in darkened rooms. (Other UV sources, such as various germicidal lights, can be more hazardous to vision.) It is best to avoid long exposure-- i.e. do not stare at the lighted process for extended periods. Process 1- Thorougly clean the item(s) to be whitened with soap and water. 2- Set the container for the cleaning process in a safe area out of reach of small children and pets.
Liquidiser or hand blender Procedure Chuck all ingredients except the Oxy into a container and mix until a smooth thick gel is formed. Just before you use it, add the Oxy in by stirring and then brush the mix onto the item to be treated. Stick it under the UV lamp. Check regularly until the yellowing has gone. ref: http://eab.abime.net/showpost.

Volume VI R021V6HIST.TXT R021V6HIST.HTML Volumes I - V are the actual history. The Appendices are in Volume VI. ______________________________ From: Rubywand 002- In 1981 it seems like 'the world' was Apple's for the taking. What happened?! What were Apple II users saying and feeling in the final years of the Computer Wars? The Computer Wars Chronicles What follows is a series of articles I originally did for COMPUTIST beginning in the late 80's. They chronicle the end of an era.
resources currently devoted to II series development, production, and marketing. Finally, speculation aside, one has only to look at what the company has done--- or, more precisely, NOT done--- to support its IIgs... NEED: Traditionally, upgrades are forced by the competition. By fall of last year, it was clear that lower prices for VGA resolution IBM clones posed a serious threat. The II series would be in serious trouble, I reasoned, if Big Green did not soon introduce a MAJOR IIgs upgrade.
plug-in upgrade, this is rumored to be a bridge board to partial Mac compatibility. That is, for a few hundred dollars, you may soon be able to turn your IIgs into a Mac Jr.! (Gosh, wasn't it just a few months ago that IBM carried off a Fortune Worst Marketing Blunder of the Decade Award for its PC Jr.?) We have, long ago, passed the point where it makes any sense to talk about maintaining II series dominance in software markets.
owners and former owners are asked to suggest company, school, and university computer purchases? Somehow, Apple is managing to convert its most valuable asset into a fatal liability. (It's not nice to skimp on your II insurance premiums!) Another Way Anticipating that, whether by design or accident, Apple may be angling for a Mac-only strategy, several respected II series supporters have joined to combat the shift and develop alternatives.
On the positive side, just such a state of flux is most likely to produce fierce competition, lower prices, increased opportunities for developers, and significant leaps in performance. One way or another, you WILL get your upgrade. If all this sounds interesting-- even, like it might be fun-- then hang on. You have the 'right stuff' for the II Revolution! Note: Bill Mensch's semi-informal "IIgs Working Group" plans one or more meetings this summer. To offer comments, ideas, etc.
success. Some "industry analysts" have suggested a low-priced Mac; but, aside from being a contradiction in terms, IF a fo r-real '90's technology Cheapo Mac were offered, the first casualty would be the current high-profit-margin Mac II. A not-for-real sub-performing Cheapo would, of course, merely repeat IBM's PC Jr. fiasco. In following through with release of GSOS 5.0, Apple demonstrates that it is not quite ready to fall on its sword. Whether Big Green has forgotten how to wield it remains to be seen.
III. Sluff-off For home users, developers, software publishers-- for everyone, in fact, with a stake in the "low end" machine-- such half-hearted support has always been as puzzling as it is frustrating. We invest hard cash in an Apple computer, join Apple clubs, subscribe to Apple publications, (slap Apple stickers on binders, use an Apple key ring, ...), fill shelves with Apple software, and buy Apple peripherals.
off, sold, or merely "supported" at current low levels, one thing seems clear. The odds are very slim that II users will ever again be an important part of Apple's empire. Consider yourself sluffed. IV. IBM: Grud-maker IBM's first PC was chiefly remarkable for what it was not. It was not a closed-box, highly complex machine packed with proprietary hardware. Featuring an out-of-the-Intel-manual design with slots for peripheral boards, it was virtually Apple's II+ 'done in business grey'.
Computer Wars I did not pick a winning manufacturer; it did pick a winning, standard platform: the "PC AT or compatible". Just look at unit sales, the quantity, quality, and range of software releases, peripherals variety, and newspaper/magazine advertising. The clincher is a pattern of plummeting prices, increasing performance, and rapid adoption of cutting-edge technology. It all adds up to the same thing: a 'standard computer'. Today, when you say "computer", everyone knows you mean "PC".
After four years of minimal 'gs support, Apple's Consummate Enlightened One has issued an inCider encyclical assuring II users of the company's continued commitment. The letter mentioned such worthwhile achievements as an improved operating system and the imminent II Hypercard (but neglected to specify where the company had been committed or how long the treatment is expected to last). Fine; but, why now? If letters, BB postings, etc.
Change-over Last fall the lone remaining advertiser-supported Apple II-only monthly announced the intention to "include Mac coverage". At the time, there seemed little reason for comment. Unlike, say, a TI-99 bulletin board I've called, a computer magazine can not be content with discussions of summer vacations and fishing trips. If a publication can't find enough II products 'action' to pay the bills, it has to find something else to talk about.
not, in five or six pages plastered with computer ads, neither the PS/1 nor the Mac LC were listed. The word "Apple" did not appear even once! (Yes; I have, in the past, found an 'LC ad. Prices were NOT listed.) Today's home programmer/ game-player/ composer/ author/ educator... is learning to shop for speed, power, and upgradability (i.e. slots!) regardless of brand name.
computing, go for the best, most II-like machine you can afford. As of Spring '91, this probably means either 1. take a ri sk on the IIgs OR 2. grab a PC-owner friend and shop the local grud establishments for a '386 PC/AT. "Here" may be the joyful realm of PC-ville. Your 'big problems' are deciding whether to 1. 2. 3. 4. add another 2MB of RAM (to handle "Windows 3.0" stuff), and/or fill that little vertical panel slot with a 1.44MB 3.
Every IIgs user is aware that most major software vendors are not releasing 'all of that great PC stuff' in IIgs format. Too little attention is given to the continuing strong support from sources like Beagle Bros, Roger Wagner, Byte Works, and MECC. Nibble and SoftDisk-GS regularly release quality software and individual programmers continue to produce useful, innovative shareware. Two recent product releases are especially encouraging. Apple's GS/OS 5.
By now it should be clear that, for the active computer user, access to a PC/AT machine is a 'given'. Along with your radio, TV, and telephone, it has become 'standard equipment'. Interestingly, it has not attracted much experimenter interest nor anything like a fanatic user group following. Today's generic PC/AT IS a good, solid machine and, by far, the best price/performance personal computing value-- besides which, it continues to absorb an overwhelming portion of major software vendor attention.
I then wrote a 256 byte "Monitor" program which watched the keyboard for hex data entry (address:data data data) and hex display and program initiation ("Run"). I got very good at typing in hex and very very good at checking data entry carefully, character by character. I still can't read a credit card number without a high expectation of mistake, but I have good habits to this day. C.T.: Even Commodore's Vic20, which appeared years later, uses easy-to-designfor static memory IC's.
C.T.: What about peripherals like the printer interface, cassette, and disk? I guess these were all coded using an assembler; right? Woz: By the time the Printer card was done with it's 256 byte ROM I may still have been coding by hand or we might have gotten our first assembler. It's unusual to this day that you plugged in a printer and it attached itself to the op-sys by means of a driver in ROM on the printer card. True plug'n play.
As an educational tool, Apple II is a sound investment. You can program it to tutor your children in most any subject, such as spelling, history, or math. But the biggest benefit--no matter how you use Apple II--is that you and your family increase familiarity with the computer itself. The more you experiment with it, the more you discover about its potential. Start by playing PONG. Then invent your own games using the input keyboard, game paddles and built-in speaker.

033- How can I use a PC mouse on my Apple II? ______________________________ From: Steve Jensen 001- How do I do the Shift Key Mod? Here's info from my files on the 'shift key mod': The one wire shiftkey mod is the oldest and simplest fix that can be made to the Apple II to get true upper and lower case operations with the shift key. Most good word processors have input routines that check the PB2 input on the game I/O port to determine if the shift key is being pressed.
I had one on my ][+. I remember a couple of wires had to be run to the motherboard. One enabled true Shift key usage. The other I can't remember. If you don't have a wire running to an IC on the motherboard, that explains why your Shift key isn't working. It could very well be the same spot where the "traditional" Shift key mod is made.

[5] & [3] [ 6] & [ 8] add .
X (horizontal) Y (vertical) Left= 0 Up= 0 Right= 255 Down= 255 This way, you have lots of active swing which makes graphics work and playing most games much easier. If you included the trim pots in your converter, adjusting for maximum active swing will be easy so long as you can get to the max 255 values with the pots at lowest resistance. (Increasing the resistance acts like lowering the value of the connected capacitor.
The mods mentioned above are not difficult, especially if you swap in a PC cable. If you want to be able to use the stick on an Apple II, then some kind of switching will be required.
As shown below, a PC stick button Output is normally an unconnected wire. Most likely, inside the computer, a PC or compatible Game Port has this line tied to a 1k-3k resistor going to +5V. So, the line will normally be at something close to +5V (= logic 1). Pressing the button grounds the line and pulls it down near to 0V (= logic 0).
[3]---- Button 1 [8]---- Ground The +5V wire is easy to find. It will go to each pot and to one side of each Button switch. The Apple2 Ground wire goes to the 'bottom' end of each fixed resistor. You do not need to label it; because it will be removed. 2. Once the wires are labeled, cut each about 1 inch from the point it goes into the cable. Remove the cable. (Keep the cable; it may come in handy for some later Apple2 project.) Now, is the time to rewire the Buttons. 3.
5. Label each of the leads coming from the PC cable. If it is still connected to a joystick, the following pic will help identify each lead: PC Joystick (15-pin male connector) [1]--------------[2] -------------[3] -------------[6] -------------[7] -------------[4] and [5] ------ +5V Button 0 X-axis Y-axis Button 1 Ground If the cable is still connected, snip the the leads once they are all labeled. If both Ground ([4] and [5]) leads are present, twist them together and treat like a single Ground lead.
Once adjusted, your 'new' stick should work fine with all PC wares.

Some indication of shrinkage or stretching on the pad seems to be normal. Our pad does not present a 'slate flat' look either; but, it works fine. Before deciding that your pad is defective, try it out on a joystick checker program. If you are using some kind of accelerator on your Apple ][, be sure to set speed to 1MHz. Similarly, you can check your software by substituting a joystick for the KoalaPad. ______________________________ 010- I have a Koala Pad with a 9-pin DIN female plug.
The above assumes that the C-64 Koala Pad will use C-64's "Fire Button" input for its main button. The second button would, then, connect to one of the four joystick switch inputs. (Actually, since all of the switch inputs, including the Fire Button, are just inputs to a port IC, any two may be the ones used to handle Koala Pad's buttons.
The header is as viewed on the motherboard. that you would plug the keypad into. The DB-15 is the female connector ______________________________ From: Rubywand 012- Is there some cable or card which lets a II user connect two joysticks? Yes. One is Paddle-Adapple from Southern California Research Group. It is a small external card with sockets for the joysticks. A ribbon cable runs into the Apple II and plugs into the 16-pin Game socket.
When the pen is in reach of the tablet (up or down) this routine will return immediately. Else it will block - fortunately, the routine checks the keyboard strobe ($C010) too and will also return if a key is pressed, even if the pen remains out of tablet's reach. After the routine has returned one can get the information: $0280 pen state: bit bit bit bit 0 1 4 4 = = = = 0 Pen down, bit 0 = 1 Pen up Previous pen state 0 Pen has been localized, its state and positions are valid.
If U1 pin 11 is near 0V and pin 19 of the KB Controller IC is not, then, there is either a break in the line connecting the pins or one or both IC's are making poor socket contact. If pin 19 of the KB Controller IC is near 0V when the CTRL key is not pressed and near 4-5V when the CTRL key is pressed, then, if you still have 'stuck CTRL key' symptoms, there is a good chance that the KB Controller IC is messed up.
The escape is a likely key for this as it is located where it can easily contact the case but does not exhibit any problems until another key is pressed and then that key will repeat. ______________________________ From: Rubywand If the KB Encoder IC or the IOU IC is loose or has pins making poor contact, you could get the symptoms described. Open the case and locate the KB Encoder (a big, 40-pin IC on the right side of the motherboard just to the right of three ROMs).

Everyone says it needs cleaning but when I look inside there is just a little dust and the rubber treads on the rollers look okay. So, how am I supposed to get my mouse any cleaner? It does sound like you have a gunked-up mouse. Rollers are whitish plastic, black plastic, or metal-- they do not have treads.
The best way to dislodge gunk is to push the 'tread' sidewise (kind of like removing a tire) as you work your way around the roller. Use the skinny longnosed pliers to pick out strips of the 'tread' as it unpeels. Use a cleaner-dampened swab to finish cleaning each roller. Use the swap to wipe around and pick out any remaining dust or gunk, replace the mouse ball, and rotate the plastic panel into place.
other large keys, take care to unhook stabilizer bars and pay attention to how the bar for each is connected. Spritz each key top with Windex, Fantastik, etc., wipe, and let soak in warm soapy water. The letters, numbers, etc. on key tops are, usually, solid plastic and should not be in any danger of getting wiped off. For sure, you would not want to use any petroleum distillate or other solvent which attacks plastic for cleaning.
______________________________ From: Mitchell Spector 024- How can I improve the feel of my original (beigekey) IIc keyboard? You can improve the feel by removing the black rubber mat. This is a spillguard; but, people complained it hindered their typing so it was removed in next generation IIc's. You can safely remove yours by just lifting it up; it's attached by a few drops of glue.

To check and fine-tune your joystick, run an Apple II joystick adjustment program such as the one on the TNILUTIL disk available from Ground or GSWV (see Q&A 001 in Csa21MAIN4.txt). If you get a range of 0-255 for Horizontal and Vertical with centers around 128 and both buttons work, the stick is properly adjusted and ready for use.
______________________________ From: George Rentovich 032- Today my IIgs started "stuttering"-- i.e. working for a bit then freezing for a bit then working again. Anyone have a fix? I have seen this before. The cause was a bad connection to the keyboard's mini-DIN-8 connector. One of the leads from the connector to the keyboard circuit board had broken its solder connection; and, the line was intermittantly connecting.

034- My GS RGB monitor takes a long time to get bright. A fix? 035- Where can I get a GS RGB monitor cable? 036- Can I replace my Apple II composite monitor with a PC VGA monitor? 037- IIgs monitor screen goes blank and power light goes out. A fix? 038- Why doesn't hires look as good on my GS RGB monitor? ______________________________ Monitor RepairMini-Manual (Q&A 001-014) 4/98 version This mini-manual describes Repairs & Adjustments which usually involve removing the case.
Basically: unplug the monitor and let sit for a day, wear goggles, work on a non-conductive table surface, do not stress CRT neck. Unplugging the monitor and letting it sit for a few hours reduces the danger of shock from stored charges; it does not eliminate it. The usual warning for this kind of work is AVOID touching two different circuit points at the same time. Like, don't touch the metal chassis and the conductive surface of the CRT at the same time. WEAR protective GOGGLES.
[|] [|] [|] insulated Anode lead going to HV module Needless to say, UNPLUG the monitor before beginning. Simply turning it off isn't good enough. 2. Get a clip lead and clip one end to a long slender screwdriver 3. Clip the other end to the metal chassis of the TV metal frame parts) (i.e the 4. Carefully! slip the screwdriver tip under the rubber flap on the top of the tube until it touches the internal wire that both holds the anode wire in place and conducts electricity.
______________________________ 006- What tools and solder should I use for repairs? For any soldering use a good quality pencil-style iron rated at 25-40 watts with a holder and sponge. Use high quality (60/40 tin/lead or better) rosin core solder (e.g. Kester "44" 20 gauge). ______________________________ 007- How do fix a Flickering, Jumping, display which sometimes collapses to a line? If the monitor exhibits major flickering, periodic collapse of the display to a line, etc.
L6B2 for a Blue screen 3. You can probably get a 10 microhenry choke at Radio Shack, or it is available for $1.28 (plus a $5 Handling charge) from Digikey Corporation at (800) 3444539. They take Mastercard, Visa, and C.O.D.. The Digikey part number is M8025ND. 4. After replacing this part, the monitor colors may need to be readjusted via the small color trimpots on the same circuit board.
______________________________ From: Rubywand 011- How do I adjust Focus and Intensity on a blurry GS RGB Monitor? These adjustments may also help cure display "bowing", etc.. Intensity and Focus controls are on the High Votage Module (black module near back of circuit board) inside the case. Follow procedure outlined earlier for safety (e.g. unplug, wait, wear goggles, ...) and removing the case. Note the position of the two controls on the HV Module (at the left, back).
What part should I get? The transistor is part Q502 on the PCB of the Applecolor RGB monitor, manufactured in 1987. This is the only power transistor in the HV section, the only one which is on a heat sink. ...." D1650 is a 2SD1650 which crosses to an ECG2331. You should be able to pick one up at your local electronics shop. Try MCM Electronics, Dalbani, etc..
If, adjusting Horizontal Hold does not fix the problem, you will probably need to remove the case. For starters, this will let you squirt some Control Cleaner into the HH control. With the case removed, you will have access to some other controls which may help solve the shimmy problem. Two are on the black High Voltage module: one nub controls base Intensity; the other controls Focus. There are also a couple small tab switches located near the back edge of the main circuit board.

and 3) the video cable exhibits lower capacitance between the center lead and the shield. You can connect your Apple II to a Monochrome or Color composite video monitor. ______________________________ From: Michael Pender and Rubywand 018- What is the usual way to connect an Apple II to a display? For a IIgs, you connect to use a video quality 'RCA cable' one of the Apple II monitors or (The IIgs has a composite color for IIgs super-res, the results the IIgs RGB monitor.
Pin 12 of the 'S02 would be bent up and connected to the output of an 'LS32 OR gate (e.g. pin 3). One of the OR gate's inputs (pin 2) would go to Pin 12 of the 'S02 socket. The other (pin 1) would go to an annunciator output. Turning ON the annunciator forces the OR gate output to "1" and eliminates Color Burst. Turning OFF the annunciator lets the OR gate output follow the 3.58MHz signal and enables Color Burst.
______________________________ From: David Empson 022- A friend with Apple //c's and IIc+'s wants to connect them to RGB monitors. What is the //c/IIc+ video port pin configuration? First, I should correct a misconception: the video port on the back of the IIc+ is _not_ an RGB port. It is a video expansion port, which provides all of the internal video generation signals used by the IIc/IIc+ which can be used to generate an alternative video output signal.
For other sources, see the Vendors listing in Csa21MAIN2 or on the web page at http://home.swbell.net/rubywand/A2FAQs3VENDORS.html . ______________________________ From: David Empson 024- What kind of RGB monitors will work with a IIc and a Laser 128? I don't know about the Laser. The IIc doesn't have built-in RGB output.
Some third-party MultiSync monitors will work on the Mac/VGA and IIgs, but these are very rare now. Most MultiSyncs do not go as low as 15 kHz. "15 kHz" and "30 kHz" refers to the horizontal scan frequency - Apple II video output has a horizontal retrace roughly 15,000 times per second. Vertical retrace is a different issue (it is much slower - usually 50 to 100 retraces per second), and most monitors are very flexible in the supported vertical retrace rate, as far as I know.

______________________________ From: Rubywand 027- Do I need to connect a monochrome monitor to my IIe to get readable 80-column text? Maybe not. Try turning down the "Color" control to get a B/W display and adjusting Brightness and Contrast. This will, possibly, make 80-column text readable on your composite color monitor. Just how readable will depend upon the particular monitor. On the popular Amdek Color-1, readability is marginal at best.

______________________________ From: James D. Keim 032- My SecondSight board bombs every time I try to run Inwords or PublishIt. What's wrong? Inwords and PublishIt use the DHR display. The SecondSight cannot emulate the DHR display and locks up the system.
display got brighter but it's still not very good. Are there any adjustments that can be made? The problem you describe is consistant with low B+ going to the flyback transformer which results in low brightness level, poor focus, and blooming when the brightness and/or screen level is turned up. More than likely if this monitor has been sitting around for awhile, the filter capacitors have gone to mush.
Unsolder the resistor, scrape the leads with a Stanley knife (gently!). Clean the solder pads with some 200 grit wet and dry sandpaper. Resolder the resistor and voila! If the resistor is OK. Then check the "kickstart" cap in the power supply (by swapping in a substitute). You can also check the STKxxxx power supply chip for bad solder joints.

1 GND The Power Supply connector pins are numbered as above. When you are sitting in front of the computer, pin 1 is nearest you. (i.e. pin 7 is nearest to the back of the motherboard). ______________________________ From: Rubywand 002- Are the power supplies for the ][+ and IIe interchangeable? Yes. The plugs are the same and the ratings are the same and they look alike.
* Except for PC power supplies, good four-output models with a -5V output seem to be rare. You can add a simple -5V regulator circuit to the -12V output to obtain -5V. As more and more new surplus power supplies are dumped, part of your shopping challenge is finding one which is _small_ enough to work well with the Apple II. This explains the price guideline. If a unit costs more than $20, the odds are pretty good that it's too big physically or electrically.
A good indicator of power problems is a noticeable drop in voltage on the +5V line as measured on the motherboard. Instead of the 4.9V - 5.0V typical for a light load, it will be 4.7V or lower. Measurements and experiments with standard IIgs power supplies indicate that the actual DC voltage drop through the 18 gauge +5V and Ground leads is only (approximately) a total of 0.04V at 3Amps, which is what a moderately "loaded" IIgs system will draw. The explanation for getting a drop of 0.2V 0.
voltages appearing across the power supply output will be larger. If you notice otherwise 'mysterious' system glitches despite having a good, solid looking power supply and/or that power supplies tend to crater when connected to your Apple II, swapping in heavier leads may be a good idea. Our current GS power supply is the one which came with the computer when it was purchased in the Fall of 1986.
Swapping-in fat leads is, technically speaking, a pretty simple job. You pop out the power supply, open it, unsolder old +5, +12, and Ground leads, solder in the new leads, close and replace the power supply. The tricky part is what hackers call the "mechanics". First, #12 or #14 gauge wire is not very flexible. Getting stranded wire (instead of solid) helps. Probably, #14 gauge is more than fat enough for all three leads. One case where #12 or #10 gauge may be worth the extra trouble is the +5V lead.
Fatter +5, +12, and Ground leads should protect you power supply and reduce circuit noise. If audio noise in your stereo card output and/or system bombing due to noise glitches were problems, they may be eliminated. A lot depends upon which cards you've installed, which slots they are in, and whether your IIgs is a ROM01 or ROM-03. The motherboard circuit traces supplying power to each Slot are fairly skimpy, especially on ROM-01 boards.
Slot 7 to the Ground plane. (You may need to scrape through green insulating lacquer to solder to the Ground plane area.) +5V: On the bottom side of the motherboard, connect two #16 gauge Red wires to the +5V point of the Power Connector socket. Connect the other end of one +5V Red wire to pin 25 of Slot 3; connect the other end of the second +5V Red wire to pin 25 of Slot 7.
______________________________ From: Rubywand 009- Why do so few GS power supplies have a fan installed? Most users depend upon System Saver GS to handle cooling because the GS case is not designed to take advantage of an internal fan. With a fan mounted on the power supply, you can, mainly, blow air around inside the case. The fan is not much good for drawing in cool air from outside or pushing hot air out.
no card produces a failure the original problem was, likely, a card which was not properly inserted. Bad Power Cord Unplug and replug the power cord at the point where it connects to the IIe. Turn ON power. Try wiggling the power cord. If the Power Supply comes ON at any time, try substituting a power cord from a known-working IIe. If this fixes the problem, you can be pretty sure that the problem was a power cord with a broken wire.
Blown Electrolytic Capacitor(s) On the end of the circuit board near the Switch are some relatively large electrolytic capacitors (typically these are tubular aluminum things with shrink-wrapped grey or light-green covers on which there are markings). Usually, they are the same size and have the same uF value and Voltage rating. One (or more) of these may be obviously blown or may just show some slime near the base.
The power supply in the //e's I fixed is made by Dyna Comp, Inc. for Apple, model no: 699-0136. Ratings are as follows: Input 240V/50Hz, Output +5V/4A, +12V/1A, -5V/.25A, -12V/.25A. Measuring the voltages on the //e motherboard I get +5V= +1.3V, +12V= +2.8V, -5V= -4.3V. If I disconnect the power supply connector from the motherboard and switch it back on, I measure the correct voltages on the connector. The fault is caused by one or two failed 1uF 35V 85deg small electrolytics.
If you open the power supply up (WITH THE MAINS PLUG OUT!) you will find a capacitor C7 near the transformer in the middle of the printed circuit board (a 220 uF 16V capacitor if I remember correctly) change it for a 220uF 25V 85 degree Centigrade rated capacitor and it should clear the problem up. ______________________________ From: Jeff Allen I've been trying to fix several dead Apple II power supplies from a local school and have managed to bring back one from the dead now.
If the PS starts to chirp when even small loads are applied (e.g. 10 Ohms across the +5V output), then it has one or more bad components or is badly offadjustment. If it has an adjustment, try cleaning the control and retry the load tests after a small change in the adjustment setting. If the chirping persists, replacing the unit with a new A2 power supply, a module from Jameco, etc. or a Buggie external PS may be the easiest cure.
Above cables made with heavy duty wires (AWG-18, with 600v insulation; colorcoded. All power supplies and cables thoroughly pre-tested prior to shipping.) 200 watt power supplies occasionally available at $3.00 extra cost, but an extra 3-4 weeks must be allowed.

During the past month, users have had to wait 2-3 weeks from payment to shipment.
______________________________ From: Scott G 017- My System Saver IIgs has gotten really noisy. How can I fix it? It may be that the fan inside the unit is showing wear. that replacing the fan is an easy and rewarding task. The good news is I knew my fan was starting to die when it sounded like it was wheezing during spin-up. The fan, a Sprite model SU2C7, uses sleave bearings, whose lifespan is determined by the lubricating oil supply in the bearings.

From: Louis Cornelio The fan I removed from my System Saver IIgs is the Comaire-Rotron Sprite SU2C1-- 'C1, not 'C7. Actually, out of the case, it seems very quite. Much of the noise seems to be rattle from contact with the plastic case of the SS ... I put down some foam weatherstrip along fan-case contact points and that did the trick! I guess there was a bit of vibraction or something. The fan is stil audible, but only slightly from the air.

With the printer OFF, hold the Form Feed button down while pressing down the ON switch. Release both buttons when the print head starts to move. To stop, turn the printer OFF. ______________________________ From: Rubywand 002- I bought an ImageWriter II and an ImageWriter LQ. What are the DIP switch settings for these printers? While a number of settings are the same; there are some differences between IW-II and IW-II LQ in DIP switch settings as well as which DIP switches are present.
German Swedish French Spanish U D U D U U D D D D D D Form Length SW-1 #4 11 inches 12 inches U D default Auto Perforation Skip SW-1 #5 No Yes U D default Character Pitch SW-1 #6 #7 10 12 17 160 cpi cpi cpi dpi U D U D U U default D D (proportional) Line Feed with Carriage Return SW-1 #8 No Yes U D CR only CR plus LF The settings for SW-2 are concerned with hardware interfacing.
SW-2 #4: If you have the 32K Memory Option, LocalTalk card, etc. installed, SW-2 #4 should be set DOWN. Otherwise, it should be set UP (the usual setting). IW-II: SW-2 #5-#6 on the IW-II are factory-set to optimize hammer firing and should be left alone by the use (On my IW-II #5 is DOWN and #6 is UP.) 'LQ: SW-2 #5-#7 (#7 is only on the 'LQ) on the IW-II LQ are used to set the number of cut sheet feeder bins attached to the printer.
No. In the ImageWriter cable, Pins 1 & 2, 3 & 5, and 6 & 8 are supposed to be swapped from one end of the cable to the other.
______________________________ 005- My ImageWriter II doesn't print! The head moves, and I can hear the pins striking the paper, but I get nothing. What's wrong? Check ribbon positioning. If the ribbon is properly positioned, then, you may need to adjust the the print head - to - roller distance (sometimes called the "paper width" adjustment). There is a small lever near the lower right side of the roller. Click-position it in a notch or two.
The idea is that the WD-40 spreads unused ink into the ribbon's print area; so, it will not work for restoring multi-Color ribbons. Since you are adding no ink, this trick is good for only one or two 'restorations'. ______________________________ 009- Can anyone tell me how to connect a printer with a "Centronics interface" to my Apple II? The Centronics interface is the standard parallel interface for many printers. To connect such a printer to an Apple II, you need a printer interface card and cable.
______________________________ 011- What are the DIP switches on my Grappler+ for? The DIP switches are used to configure your card for a series of different printers out there.
Switch one doesn't matter unless you want to send a high bit through. If you don't care about printing high ASCII (language characters, legal and math symbols, box edges), then it can be set either way. ______________________________ From: Scott G 012- What printers will the Harmonie drivers work with on my GS? The 4550 automatically senses Epson LQ code and turns on emulation. It is like if the DIP switch were set to automatic in older BJC models.
______________________________ From: Supertimer 013- I have recently acquired an Apple IIGS and I want to use my Panasonic PanaPrinter parallel dot matrix printer with it. What is the best parallel card to use with my IIGS? The best parallel card is no parallel card. The IIGS is has serial ports and the best way to use parallel printers is with a serial to parallel converter. Global Computer Supplies, http://www.globalcomputer.com/ , has a bidirectional model (TAC6180) that is excellent.
______________________________ From: Owen Aaland 015- I have a problem with getting fonts recognized. I copied the entire contents of one PRODOS Volume (named "AA") to another hard drive with a different volume name for use on another GS. When I launch AWGS or any other GS word processor on the second GS, I am told to "insert disk AA" when a font is requested.
(If you have a cable connecting the printer port to the printer, then "Select a Port" would be "Printer" and "Select a Printer Type" would be "ImageWriter" or whatever you have. If you have a parallel card in Slot 1 then "Select a Port" would be "GrapplerPlus" or whatever, and "Select a Printer Type" would be "DeskJet560C.HAR" or whatever you have.

______________________________ From: Rubywand, M Kelsey, Mark, Glynne Tolar 020- How can I connect my Imagewriter II to a PC? You can do Text printouts from your PC to IW-II by selecting the C-Itoh 8510 as your printer in Windows 3.1 up through at least ME. (Just go to settings: printers: new and select the c-itoh 8510.) The connection from the IW-II must go to a serial port-- e.g. COM-1 or COM-2. The cabling information shown below is from the the Imagewriter II manual.
Socket-A TXD RXD RTS CTS DSR & DCD GND DTR 2 3 4 5 6&8 7 20 Socket-B -> <-> <<--> 3 2 5 4 20 7 6&8 RXD TXD CTS RTS DTR GND DSR & DCD The two cables (plus gender/9-pin adapters as needed) give you the connection described in the IW-II manual. A CrossWorks cable (plus adapters as needed) is supposed to work, too. Either the homebrew cable or one of the combinations of existing cables mentioned should allow a hardware handshaking connection at 9600 baud.

______________________________ From: Todd Whitesel 001- If the GS only has eight output chanels, then it would seen to me that it could only play eight different sounds at a time. So how can I digitize fifteen different sounds and play them all back simultaneously? To summarize the following lecture: There are 32 oscillators (16 generators) and 16 channels. Not all are used for actual sound output.
'channel number' setting for the oscillator and the last one simply changes voltage from about 3 volts to about 0.5 (for you EE folks out there, this is the negative edge of an output-valid strobe). External hardware is responsible for splitting off the various channels (4 bits means that there can be 16 of them) and outputting them seperately. The motherboard hardware just ignores the channel setting and mixes all the sound outputs into the speaker/earphone.
the front two outputs. I have built this circuit on a bread board but need to make a PC board to make a better sounding circuit. Also the output impedance should be set to 75K ohms but I haven't yet gotten around to it. To make sound in stereo or quad all you have to do is place the binary address of the channel you wish the sound to have in the control regsister for the ocsilator (the tools can do this) and there you have it.

______________________________ From: Rubywand 003- My IIgs has a stereo cable plugged right into the Sound Output jack. Isn't that two-channel sound? Nope; and, it is not "stereo" either. The jack is a standard stereo jack; but, the "Left" and "Right" outputs are connected to a single 'composite' source. Possibly, Apple originally intended to supply two-channel sound; perhaps, the idea was just to simplify connections to stereo systems.
Volts) comes from the slot into which the board is plugged. The outputs go to "RCA-type" hi-fi jacks mounted on the rear of the board for easy access via standard audio cables. When placing the jacks, be sure to allow space (between the jacks and rear of the computer) for the cable plugs or arrange for the jacks to line up with an opening. The J-25 connection is via a 7-pin mini-molex ribbon cable.
______________________________ From: Mitchell Spector 007- I just got a Phasor Sound Card and now I need some info. What are the 4 DIP switches used for? What are the 2 POTs used for? And, where can I get programming information? The Phasor is a great sound card. Offers you 12 sound channels (using all sorts of wave-form patterns and effects, simular to FM-synthesis in IBMs), 4 white noise generators (synthesized drums, etc) and a 1-voice synthesized speech channel, expandable to 2 speech channels.
http://www.apple2.org.za/mirrors/ground.icaen.uiowa.edu/MiscInfo/Hardware/ [quote] If you don't mind putting together a few parts, you can build your own adapter, though (explanation follows): GS Analog 10-500 uF In ---------------+------------+----+------------||------ >> | | | -+-++ To CD player, 5V Zener /_\ Signal /_\ = 1.5V microphone, diode | Diode | - Battery etc.
If you can get the file http://cassius.ee.su.oz.au/~adrianw/gsaudioin.bsq there's proof there that it all works (a raw sound file I made).
MockingBoard C is simply a MB-A that has been upgraded by plugging in one speech chip. Suggested retail price is $179.00. (There was an 'undocumented' upgrade, obtainable by plugging in the other speech chip, which allowed the board to "sing harmony" with itself!) MockingBoard D is a stereo music, sound and speech synthesizer for the Apple IIc. It connects to a IIc through a serial port and is, of course, external (unlike the Slot board models for other Apple II's).
The Enable/Disable register also lets you decide whether or not to send the Noise Generator's output through a Channel. Three bits let you decide which Channel(s) the NG's output will go through. For example, you can enable NG output through Channels A and C but not through B; or, disable NG output through all three Channels, etc.. If, for example, Channel A's Tone oscillator output is enabled and NG output is enabled for Channel A, then, a mixed Tone + NG signal will go through Channel A.

______________________________ From: Tom Mage 012- How can I get 'regular Apple sound' (like BEEPs, etc.) to play through my Mockingboard's outputs? I recently got a Mockingboard C, which, it turns out, has a plug and cable specifically for connecting in sound from the Speaker! (Most likely, the MB A has a similar connection.
______________________________ From: Michael Mahon For the vast majority of connections to external amplifiers, a nonpolarized capacitor is not required in this circuit, precisely _because_ the transistor side of the capacitor never goes below ground. A 4.7 uF capacitor, with the (+) side toward the transistor collector and the (-) side toward the amplifier will do the job nicely.
From: Clayburn Juniel/Effective Software Solutions Hey, what about Music Composer? MIDI playback. It's much better than synthLAB for doing Just a note.

All Apple II computers can produce "Old Apple" sound without any special boards or add-ons.
______________________________ From: Rick Diffley 022- How can get more System Sounds for my GS? IF you have HCGS (HyperCard GS) then, one way to get System Sounds is to place a HCGS stack with rSounds in the Sound folder. You'll have plenty of new sounds to use with the Sound CDev.
______________________________ 024- Using Sound Shop and similar utilities, I get static and scratchiness on my GS sound samples and, sometimes, hum. What's wrong and how can I get better recordings? There are several ways to get "static" when recording sounds on your GS. One is to have incorrect settings for the sound recording program. If input level is set too low, you may be recording relatively more noise than sound.
helps reduce noise. However, any GS may exhibit Slot noise when a few powersucking boards (e.g. an accelerator) are plugged in. For ways to reduce noise see the Power Supplies and Cooling FAQs file CSA2POWER.TXT. Check Q&A related to power supply enhamcements and/or possible swaps. Also check Q&A 019. ______________________________ 026- My IIgs has no sound from the internal speaker. How can I fix this? The fix _may_ be fairly easy.

______________________________ From: Rodney Hester and Rubywand 030- My GS stereo board's sound output is very low and noisy. A fix? An output cable may be poorly connected or defective-- check for breaks and shorts; or, a chip or connection on the board may be loose or defective. A perfectly good card correctly connected with good cables can exhibit these symptoms in a IIgs with an overloaded power supply, even when the computer seems to be working okay otherwise.

______________________________ From: Rubywand 001- How do I transfer files between my Apple and a PC or Mac? The best, most flak-free way to move stuff between your Apple II and PC or Mac is via a standard NULL modem transfer. (A NULL modem connection joins a serial port of the Apple II to a serial port of a PC, Mac, etc. via a NULL modem connector joining modem cables from each computer. Radio Shack and ThinkStuff sell NULL modem connectors/cables.
On a PC, you can install a program called MacDrive 98. This program allows Windows 95 to read, write, and format HFS volumes. To transfer files from HFS media to ProDOS disk you can use A2fx or HfsLink. The IIe, etc. must have connected to access 800k HFS diskettes. This method which can not run a version of System supporting the on the IIe, IIc, or IIc+ an 800k 3.5" drive would also work for IIgs's HFS FST. ______________________________ From: Ruud For Mac users, if the file arrives in a .zip or .
______________________________ From: Bill Mackin 003- I've heard of ADT and ap2222pc. How do these packages work for transferring Apple II disks between an Apple II and a PC? Yesterday I downloaded ap2222pc.zip written by some guy in Hong Kong. It copies whole Apple disk images over to the PC, or PC to Apple, or individual files back and forth! You buy a 25-pin male parallel port connector and two 8-pin DIP sockets from Radio Shack. He gives the wiring diagram for connecting 9 wires between them.
ADTPro- Recent release for ProDOS which runs on 64k Apple II (with the Apple SSC card) and with the Apple IIgs native modem port at 115kbps. This distribution also uncludes a new interface for the other side. ADT is practically always distributed as a .zip file including at least an Apple II and PC program plus directions for transferring the Apple II program dump file to your Apple II, setting up, and operation. One distribution, ADT_2004.
Since a NULL a modem connection generally requires fewer control signals than a connection to a real modem, there are many workable variations of this setup. One pretty good try is to use a serial printer cable connected to the Apple II-- for example, on a IIgs you can use a Mac Imagewriter I cable. This eliminates the need for a NULL modem adapter. (You will probably need a FemaleFemale plug adapter to connect to the PC* COM port or PC modem cable.
If you can not use a separate PC or Mac port for your connection to the Apple II, you can move the PC modem cable connection from your net modem to the NULL modem for doing transfers or use a switch box. For a GS, the recommended modem cable is a "high speed" type which allows hardware handshaking and, if present, this option should be set in the GS telecom software. The same is true for other Apple II's with serial ports or boards (like the Super Serial Card) which can do hardware handshaking.
Finally, you will select the file or files to send or "Open". At the start, some experimentation is likely to be involved in getting your computer-to-computer transfers going. For example, you may find that it matters which end you start first. (When using ZLink on the Apple II and doing an Xmodem transfer, start the Send side first, then the Receive side.) If your setup works best starting Receive first, you may find that one telecom program or the other does not give you enough time to start Send-- i.e.
them in a .SHK file, Z-modem them to the PC, and use Nulib (v3.24) to unshrink the files in PC Text format. Otherwise, you are probably better off doing a Text transfer. Set your A2 telecom program to "send LF's". If there is a "Prompting" option it should be OFF. Do an "ASCII Text", "Plain Text", etc. Send. The PC telecom program should be set to Receive Text if this option is available.

______________________________ From: David Empson, Richard Der, Rubywand, Hal Bouma 010- What is the maximum modemming speed I can get from my Apple II? IIe and earlier Apple II's: These require a serial card which usually plugs into Slot 2. In general, the card determines maximum connection speed for these computers. Many early serial cards max out at 9600 baud. Apple's Super Serial Card (SSC) and compatible serial cards max out at 19,200 baud.
____________________________ From: Gareth Jones 011- What telecom programs run on Apple II computers? KERMIT: Available in DOS 3.3 and ProDOS versions, this freeware runs on any Apple II. (On a GS, you need to turn the "DCD Detect" option OFF in the modem control panel.) KERMIT is little harder to set up and use than some other telecom software; but, works fine for Kermit and X-Modem transfers. It supports VT52, VT100, and dumb terminal emulations.
Another very good program is Modem MGR from MGR Software. It runs on any Apple II and works with a wide range of modems, 80-column boards, and clock cards. MM supports popular protocols from X-modem through Z-modem and many terminal emulations. ______________________________ From: Supertimer Agate offers Z-modem. Z-modem is a much better protocol, with a resume function (web browsers should take note) and powerful CRC-32 error checking.
Note that RS-232-C signals on the SSC use negative-true logic; that is, they are true at 0v and false at +5 volts. DIP Switch Settings (up is ON for each switch) These set the default operation of the SSC. The settings may be overridden via commands entered from the keyboard or from software.
For modem operation, SW1-7 should always be ON and SW2-7 should always be OFF. *For printer operation, the setting may vary. If using an Imagewriter II SW1-7 should be ON and SW2-7 should be OFF. SW2 Dip Switch Settings Switches SW2-1 through SW2-4 functions depend upon whether modem or printer operation is enabled.
SW2-5 enables automatic line feed generation. on auto-send a linefeed after sending a CR off no linefeed auto-send SW2-6 enables interrupts.
An unmodified SSC can access the external oscillator circuit via software to get 115,200 bits per second. All you have to do is dump $10 into $C0AB instead of the $1F that's normally there. Although not supported in many applications, the new 115k setting has been added to ADT 1.23. Note: Some SSC boards may need to upgrade to a later version of the 6551 ACIA chip to function reliably at higher speeds. ______________________________ From: Kevin M.
o Switch 3: IRQ from 6818 o Switch 4: NMI from 6818 ______________________________ From: Cyrus Roton 015- What are the switch settings for the old Apple Serial Interface card? The switch settings are as follows: 1 on off on off on off on off sw 4 5 on off on off sw 7 2 on on off off on on off off 3 on on on on off off off off baud rate 110 134.
______________________________ From: David Empson 017- What kind of cable should I use to connect a modem to my IIc? Here is the pinout of the IIc serial port looking at the back of the computer: DIN-5F (female) socket with Apple's numbering 5 1 4 2 3 The functions are: 1 2 3 4 5 Handshake Out (nominally DTR) Data Out (TxD) Ground Data In (RxD) Handshake In (nominally DSR) To connect a IIc to a typical modem use the following pinout for a non-hardware handshaking cable: IIc DIN-5M Modem Dsub-25M 1 2
The IIc cannot do hardware handshaking** very well, but this is as close as you can get: IIc DIN-5M Modem Dsub-25M 1 2 3 4 5 4 2 7 3 5 Handshake Out Data Out Ground Data In Handshake In RTS TxD Gnd RxD CTS DIN-5 plug Dsub-25M male connector 1 5 2 4 3 ,--------/ /---------. \ 1 2 ... 12 13 / \ 14 ... 25 / `------/ /-------' ** Note that you need comm software which supports hardware handshaking on the IIc to do this properly.
Yes; the cable to use is a Macintosh to Hayes Modem cable. This can be found in any computer store. Just ask for a Mac to modem cable. All new Mac cables are usually hardware handshake cables, so you should have no trouble with higher speeds. ______________________________ From: Aaron Heiss 019- How can I program the Super Serial Card in assembly language? You can access and control the SSC using these four I/O addresses ("s"= Slot location of card +8; e.g.
2- "Phone Number" page Connect using= Direct to Com 1 (or whatever PC Com port you will use) Click on Configure* and set Bits per second= 300 Data bits= 8 Parity= None Stop bits= 1 Flow control= None (You should not need to change any Advanced settings) Click OK *Note: This settings window comes up automatically on some versions.
______________________________ From: Dave Althoff and Jeff Blakeney 021- How do I get an Applesoft program into a PC-DOS computer in text format? Both computers have modems, but I have no terminal program for the Apple. Make sure that your serial ports are connected together, and run the comm program on your PC. Now, for our purposes, lets assume you have the serial card in Slot #2.
Before that, I was using something that worked except at 2400: ATX4&M0Y0\N2 ______________________________ From: John M. Davies Just pointing out, the INIT string is not a function of the comm program, it is a command to the modem itself, so any good comms package should be able to send any sort of init string to the modem. ATZ is the standard Hayes command to 'RESET MODEM TO DEFAULT' settings, and must be on it's own line, hence the character is required.
______________________________ From: Steph and Gist 024- What cable can I use to do Apple IIc <---> PC ADT transfers? Below is the pinout for a IIc NULL modem cable for use with the ADT disk image transfer utility. It shows signal names and signal directions. Both 9 and 25-pin numbering is shown for the PC connector end. For the IIc plug, DIN-5 pin numbers are listed with traditional Apple pin numbers in parenthensis ...
wait-state and by sending sample-files from the IIc by issuing a 'send' command from ADT to Hyperterm. I discovered that the problem was different numbering of the onboard COM ports in DOS vs. Win98. That is, in DOS COM #1, #2 corresponded to WIN98 COM #3, #4. Once this was straightened out, everything worked.

Downloading via a Browser Some major Apple II sites are FTP sites-- places you get to via an ftp:// URL. FTP connections tend have a pretty raw look-- instead of colorful backgrounds, pictures, fancy buttons, etc., what you see is mainly text showing folder and file names. You may get folder icons and, perhaps, some simple icon next to each file name. Today, many Apple II sites are web sites with pages you get to via an http:// URL.
Another pretty good alternative is to go ahead and download the .shk, etc. file and use a PC utility named "Uncook" to try producing a copy with the corruption removed. Uncook was 'discovered' by GS Ed (manager of the ACN Florida archive); and tests indicate that it usually succeeds when the file is corrupted. If the file is not corrupted, Uncook may produce a messed up copy! Fortunately, it is pretty easy to tell when the latter occurs.
C:\Downloads whenever you connect to Asimov. If you want downloads to go into D:\TempStuff, you can pick this destination. Another situation in which you may wish to change the local folder is when uploading files to a site. Practically all programs and compressed disks will be in .SHK, .SDK, .DSK, or some other "binary" form. In fact, "Binary" should nearly always be your download/upload mode setting, even when downloading (or uploading) Text files.
off the Binary II prefix during transfer. GS-ShrinkIt and 8-bit ShrinkIt will remove a Binary II prefix from .shk, etc. ShrinkIt files.) The file may be okay but incorrectly named. For example, an .sys or .bin file may be shrinked but still uploaded as an ".sys" or ".bin" file (instead of ".shk"). Or, an .shk file may be uploaded in binscii form as an ".shk" file. (Such a file should end with ".bsq".) When a downloaded .shk or .
______________________________ 004- I need some help with uploading. I uploaded a large file to an Apple II ftp site but nobody seems able to download it without ending up with garbage. What's wrong? Uploading files to an FTP site is a fairly simple process-- basically, it's pretty close to the reverse of downloading described above. For example, to upload a group of Apple IIgs files named "NARFGAME" you would ...
Click "Yes" when asked if you want to upload the file(s). If the site accepts your upload you will get some kind of message indicating this somewhere on your screen-- maybe at the bottom-saying "upload successful", "upload done", etc.. Uploading via an FTP program o If you prefer using an ftp program (e.g. WS_FTP, Cute FTP, etc.) or the ftp site will not permit browser uploads, start your ftp program.
loader does not have an A2 telecom program which automatically strips off the header during NULL modem transfers (or if "Binary Down" is turned OFF), the Text file will look like garbage on the Apple II as well. o Too many old-time Apple II users still insist upon doing a binscii conversion of all .SHK files before uploading them. When, as sometimes happens, a binscii'd .SHK file is uploaded as an ".SHK" file, downloaders end up with a ".SHK file which ShrinkIt cannot unshrink".
All of the above would be uploaded in "binary" mode. Text which is intended to be readable on-line should be uploaded as plain Text in "ASCII" or "Text" mode or, on most sites today, in binary mode. Whenever you upload a game, utility, etc. to an ftp site, it's a good idea to also upload a brief Text file with a description of the uploaded item. For example, after uploading NARFGAME2.SHK (in binary mode), you could upload a brief description in a Text file named NARFGAME.TXT (in Text or binary mode). II.
When you are done reading and replying, you exit the program and it creates a reply file, called a REP packet. The next time you connect, you simply upload the REP to the maildoor. The maildoor will decide what goes where and your messages will enter cyberspace pronto! To use 2qwk! you will need an enhanced Apple IIe, IIc, or IIgs, with at least 128k RAM and drive space to hold the QWK data. The program itself will fit on a 5.25" disk with plenty of room to spare.
______________________________ 011- What is a "Binary II" header? A Binary II header is a small block of code tacked onto some Apple II files. Sometimes, this is referred to as a "binary wrapper". Mainly, the Binary II header contains filetype information. The purpose of Binary II is to allow Apple II users to download files and have them show up with the correct filetype. (Otherwise, a downloaded file tends to show up as a TXT type file.
ftp files by email. I think that by sending HELP to that address you will get the rules of how to do it. How about surfing the net? Well, I send messages to www4mail@unganisha.idrc.ca or www4mail@web.bellanet.org with SUBJECT anything (it will be ignored) and message: get http://www .... .html (i.e. the URL of the document) You can expect to receive the www-document in your email box. If you need to look at the source files of the www-page, send message: get http://www .... .
You may have noticed that you get good IE downloads of .zip files from some sites-- WinZip unzips the files with no problem. But, from other sites, the .zip files cannot easily be unzipped or, sometimes, not at all. One idea I've come across is that, starting with IE 6, Microsoft began to require that download sites provide information about .zip files, perhaps other kinds of files, too. If the information is supplied, the file arrives okay. If not, you get a 'bad' .zip file.

Zip Q&A 001-008 info mainly from the 1996 II Alive review by Eric Dietrich 001- What is a "Zip drive"? The typical Zip drive is a 100MB removable media system. Cobalt blue in color, the popular external drive is compact and light-- about the same size as the newer external modems. The 100s "SCSI Zip" connects to the any computer with a SCSI port including the Apple IIgs or IIe equipped with a SCSI interface card. The Zip drive is made by Iomega. Price for the 100MB external model is around $130.
have. The Apple cards are no longer made or supported; but, you may be able to buy one at a swap meet. The Sequential Systems RamFAST has DMA plus an on-board cache of either 256kB or 1MB, making it the fastest interface available. RamFAST has a full set of utilities in ROM, so, it's easy to set up, too. ______________________________ From: Willie Yeo Apple Hi-Speed SCSI card users need to remember that these cards normally do not supply termination power.
comp.sys.apple2, or, even, read the documentation that came with your SCSI card (when all else fails ...). ______________________________ 006- How do I get started using the Zip drive? Once your drive is connected, its time to start your machine and prepare a Zip disk for use. The Advanced Disk Utility (on a IIgs) or the utility that came with your SCSI card can do formatting and set up partitions (i.e. create named "Volumes").
Shared HFS GS/Mac disks should be formatted on the IIGS because the IIGS tends to provide a format that is acceptable to both platforms while the Mac tends to ignore the needs of the IIGS. Besides the standard Apple Disk Utility (ADU), you will need GenEx. GenEx extracts the generic Mac SCSI driver from ADU's resource fork and puts it into the IIGS' drivers folder. Thus, when ADU looks in that folder, it finds and installs the driver and does not give the "no mac driver found" error.
MUG! is an NDA (New Desk Accessory) which must be started from the 'Apple menu' (click on the Apple symbol) available at the top of a typical GS 'desktop'-type display. One thing to be aware of is that MUG! should be used from an application other than Finder (the usual main GS "desktop display"). The Finder and many other applications will do a drive check, find the MS-DOS Zip disk, and respond with something like: "Installed FSTs do not recognize disk, do you wish to format it or eject it?".
As for getting your GS to recognize the Zipdrive in all applications: 1.) Turn on your Zipdrive 2.) Turn on your external HD 3.) Turn on the GS 4.) Put the Zipdisk in the drive before GSOS is booted so that it may be scanned and recognized. Last, if you are working on the GS for a long time and suddenly the Zipdrive Icons don't pop up when you load Finder, simply eject the zipdisk and push it back into the drive.
______________________________ From: Rubywand 012- Which SCSI interface works best with a Zip Drive? Your best choice is the version 3.01f RamFAST. Along with good speed, Direct Memory Access support, and on-ROM utilities, you also get an interface which permits ejecting a Zip disk and mounting a new Zip disk from the System 6 Finder. (There is no need to restart the system in order to swap disks.) The RamFAST 3.01f also supports a variety of CD-ROM drives and hard disk drives.
______________________________ From: Rubywand 014- Should I just let the System Finder handle formatting of new Zip disks? If you are at the usual System Desktop display and insert a new, "blank" Zip disk, you will be told that the disk's format is not recognized and asked if you want to have it formatted.
______________________________ 016- Often, when I power-ON my computer, the disk in my Zip Drive is not recognized. What's the problem? Almost immediately after power-up, your SCSI interface begins checking for devices. Most likely, the problem is that your SCSI interface checks the Zip Drive before it is ready and decides no disk is present. The cure is to put your Zip Drive, CD-ROM drive, etc. on a separate power line. These devices should be switched ON 5-10 seconds before powering- ON the computer.
______________________________ From: Dan Brown, KE6MKS 019- What's a good utility for doing tape backups on the GS? Here follows an unpaid testimonial: The Tim Grams GS desktop SCSI backup utility called "GSTape" works great! I got it for an old Apple Tape 40SC, did several backup/restores, and then ran across a 2GB DAT drive.
GSOS or I believe there are some 8 bit programs, too) that knows how to store files on the tape. Open Advanced Disk Utilities when in GSOS and see if the SCSITAPE unit is present-- then you will know the drive was identified ok. Then the next test-see if you can backup. Open archiver, set your "backup to..." device as SCSITAPE and hit start. When OK. If it like your the thing backup to backups.
______________________________ From: Supertimer 022- I've heard that Apple's Hi-Speed SCSI card does not allow swapping Zip disks without turning OFF the computer. Is this true? No. The Apple Hi-Speed SCSI interface allows ejecting and swapping removable disks. With a partitioned Zip disk (or CD-ROM), you have to lasso or shift-click to highlight all the partitions and drag them to the trash to eject the disk. (As long as one partition remains on the desktop, the disk stays in.
I've had success with repairing the directories on disks destroyed by 'click death' drives. I'd tried reformatting the disks on Win95 and 98 machines but the format utility (even long format with verify) gives up too quickly and reports the disk is either locked or damaged. Scandisk refuses to even look at the disks and reports there is something wrong with them. Using the Win3.1 guiutil.exe on an old 486, I was able to reformat thedisks and they now work fine on all the various machines I've tried them on.
______________________________ From: Supertimer 026- How do I restart my HS SCSI + Zip when the Zip deactivates? The problem is with the Apple SCSI driver. The Zip drive normally deactivates itself after a period of time to conserve energy. The Apple SCSI driver fails to reactivate the Zip when the IIGS tries to access it. If this happens in some programs, data can get corrupted. If it happens in the Finder, the Finder will ask you if you want to format the Zip disk.
