Introduction Your Epson® Equity™ II+ personal computer is a versatile, highperformance system that offers you a wide variety of choices. First you choose between two models of the Equity II+ main unit, then select the monitor and peripherals you want to use with it to assemble the configuration that does the most for you. The Equity II+ main unit is available in these models: l One 1.2MB (megabyte) high-density floppy disk drive l One 1.2MB floppy disk drive and one 40MB internal hard disk drive.
You can add memory expansion option cards to increase the amount of internal memory in your Equity II+, and you can add an 80287 math coprocessor (which is not an option card but installs on the main circuit board). You can also use most cards for the IBM® Personal Computer, PC XT™, and PC AT™ on the Equity II+. Check with your Epson dealer from time to time to find out which peripherals and. option cards are available.
The last section of this manual describes the diagnostics programs for your Equity II+. You run these diagnostics programs the first time you set up your system and any time you change the configuration of your Equity II+.
Chapter 1 Setting Up Your System Setting up your Epson Equity II+ personal computer is easy. Just follow the steps in this chapter- You’ll find a quick guide to these steps on the inside back cover. 1 Unpacking As you remove your system components from their cartons, be sure to inspect each piece. If anything is missing or looks damaged, consult your Epson dealer.
Be sure to keep your packing materials. They provide the best protection possible for your computer if you need to move or ship it later. Removing the disk drive protector sheet A cardboard sheet occupies the diskette slot in the floppy disk drive. This sheet is inserted at the factory to protect the read/write heads. Be sure to remove it before you connect any cables. Turn up the latch that covers the disk slot until it is horizontal. Carefully pull out the sheet.
l l Appropriate power sources. To prevent static charges, connect all your equipment to 3-prong, 120-volt grounded outlets. You need one outlet for the main unit, one for the monitor, and additional outlets for a printer and any other peripherals. The auxiliary power outlet on the rear panel of the Equity II+ reduces the number of wall outlets you need. No electromagnetic interference. Locate your system away from any electrical device that generates an electromagnetic field.
If you have special computer furniture or want to customize your setup, you can arrange your system components to suit your own needs. Before you connect the cables, take a look at the front and back panels of the main unit. The front panel Figure 1-2 identifies the various components on the front panel. To view the keyboard socket and control switches, gently press in each cover on the lower left side of the front panel. This releases the cover and you can gently pull it down to view the switches.
Slots for optional disk drives. You can add another floppy disk drive (1.44MB, 1.2MB, 720KB, or 360KB) and/or hard disk drive in these slots. All Equity II+ units come with at least one 1.2MB floppy disk drive. Hard disk drive light. A green light indicates that the drive is being accessed. To avoid losing data, do not turn off the computer’s power when this light is on. Power light. When the light is on, the power is on.
WARNING: Connect all your peripherals before you plug in the power cable. After you plug in the power cable, always turn off the power switch before you connect or disconnect any peripheral. Voltage switch. Leave this switch at 115V for USA and Canadian use. Slide the switch to the right to select 230V for use in other countries (as necessary). AC OUTLET Auxiliary power outlet. You can plug some monitors (and other types of peripherals) into the main unit here, instead of a wall outlet.
Figure 1-4. Connecting the power cord 5 Connecting a Video Monitor The procedure you use to connect your monitor to the main unit depends on the type of monitor you have. Refer to your monitor manual for detailed instructions or follow the general guidelines below. Note: Your dealer may have installed a video card in your main unit to control your monitor. If not, you need to install it before you can connect your monitor.
Figure 1-5. Connecting the monitor The monitor type must match the video card in the main unit. If you have a color card, you can use one of two connectors: a nine-pin, female D-connector for RGB monitors or an RCA connector for composite video monitors. Consult Table l-l to make sure your card and monitor match. Table 1-1.
4. Plug the monitor’s power cable first into the power inlet on the monitor and then into an electrical outlet. Note: If a monochrome monitor has the proper type of plug, you can plug it into the auxiliary outlet on the back of the Equity II+ main unit. 5. Set the monitor switch on the front panel of the main unit for the type of monitor you are using. (See Figure 1-2.) Slide the switch to the left for a monochrome monitor or to the right for a color monitor.
You can tilt the angle of the keyboard by adjusting the legs on the bottom. To adjust the legs, turn the keyboard over and lift each leg upward until it locks into place, as shown in Figure 1-7. You can adjust the legs to two different positions, or leave them flat. Figure 1-7.
7 Connecting a Printer The Equity II+ has both parallel and serial interfaces. You can easily connect a printer or plotter that has either type of interface-just follow the instructions below. Epson offers a full range of printer products. Consult your dealer for more information. Parallel interface The Equity II+ parallel interface is Centronics®-compatible and uses a DB-25S connector. Most Epson printers have parallel interfaces.
.4. Connect the other end of the cable to the printer as shown in Figure 1-9. To secure the cable, tighten the squeeze locks at each side of the printer port and push them into the connectors on each side of the cable. Figure 1-9. Connecting the printer 5. Plug the printer’s power cable into an electrical outlet. Serial interface If you have a printer (or another peripheral such as a modem) with a serial interface, connect it to the serial (RS-232C) port at the back of the main unit.
The Equity II+ character set The Equity II+ uses a special character set that assigns graphics and international characters to some of the ASCII codes. In most cases, if you try to print these characters on a standard printer, you get italic characters instead. Some Epson printers support the IBM character set (the character set the Equity II+ uses) as a standard feature, and others can be adapted.
Turning on the power switch Now you are ready to turn on your system. It is a good idea to turn on the monitor and any peripheral devices before you turn on the main unit. First, make sure the power cord is plugged into the power inlet on the back panel of the main unit. Then plug the power cable into a 3-prong, 120-volt, grounded electrical outlet. Turn on the monitor so you can see the messages that appear as your computer starts up. If you have a printer or other peripheral device, turn it on next.
do it again if you change your system configuration-by adding a disk drive, for example-or to change the system date or time. See the Diagnostics section at the back of this manual for instructions.

Chapter 2 Using the Equity II+ This chapter covers some basic procedures for using your Equity II+ computer and keyboard. Inserting and Removing Diskettes To insert a diskette into the 1.2MB floppy disk drive, hold it with the label face up and the write-protect notch to the left (so that the read/write slot is away from you). Then slide it into the disk drive as shown in Figure 2-1. When the diskette is all the way in, turn the latch down until it locks into the vertical position.
To remove the diskette, turn the latch up until it is horizontal and the diskette pops out. Carefully pull out the diskette, place it in its protective envelope, and store it properly, such as in a special diskette container. If you have an optional floppy disk drive with a disk drive button, insert the diskette the same way as for a 1.2MB drive (with the label facing up). ‘When it is all the way in, press the disk drive button to lock it in place.
Table 2-1. Special keys Esc F1 - F 1 2 Print Screen Sys Rq Scroll Lock Pause Break Cancels the current command line or operation. Perform special functions within application programs. Prints the screen display on a line printer. Generates the System Request function. In some applications, controls scrolling. Suspends current operation. Terminates current operation. The Num Lock, Caps Lock, and Scroll Lock keys work as toggles when you press them.
To change the speed, move the CPU SPEED switch on the front panel. See Figure 2-3. Figure 2-3. CPU speed switch When the computer is running at 8 MHz, the power light is orange, and at 12 MHz, the light is green. Resetting the Computer You can reset the computer to load a different operating system or to reload the current operating system. For example, if an error occurs and the computer does not respond to your keyboard commands, you can reset the computer and try the same operation again.
There are three ways to reset. Because each is more powerful than the last, try them in the order listed here: If you are using MS-DOS, hold down Ctrl and Alt and press the Del key on the numeric keypad at the right of the keyboard. The screen goes blank for a moment and then MS-DOS reloads. (MS-DOS must either be on the diskette or be autobootable from the hard disk.) If this does not correct the problem, try the second method. Press the RESET button on the front panel.

Chapter 3 Using Disks and Disk Drives The disk drives in your computer allow you to store data on disk, and retrieve and use stored data when you like. All Equity II+ systems have at least one floppy disk drive; you may also have a hard disk drive and/or a second floppy disk drive in your system. This chapter explains how disks work and tells you how to: l Choose floppy disks l Care for your disks and disk drives l Protect your data l Use a single floppy disk drive l Use a hard disk drive.
Choosing Diskette Drives for the Equity II+ Your computer has one or more of the following types of drives: 360KB drive-Uses S&inch, double-sided, doubledensity, 360KB diskettes. (You can also use single-sided, 160KB or 180KB diskettes.) These diskettes contain 40 tracks per side, 8 or 9 sectors per track, and hold up to 360KB of information. (With 8 sectors per track, a diskette holds 320KB.) KB stands for kilobyte; each kilobyte equals 1024 bytes. 1.2MB drive-Uses 5%inch, double-sided, high-density, 1.
Table 3-2. 3Xhch drive/diskette compatibility Drive type Diskette types it can read from and write to 720KB 1.44MB 720KB 720KB, 1.44MB If you have any combination of the above drives (360KB, 1.2MB, 720KB, and 1.44MB), you can copy files from one drive to another (using the COPY command) as long as the correct diskette type is in each drive. You can also copy files between a hard disk and any type of diskette.
Never touch a diskette’s magnetic surface. The oils on your fingertips can damage it. Always hold a diskette by its protective jacket. On a 3%inch diskette, do not expose the diskette’s surface by sliding the metal plate. Store diskettes properly. When they are not in use, keep diskettes in their protective envelopes and store them in a diskette container. Do not place anything on top of your diskettes and be sure they do not bend or sag. They do not rotate properly in the drive if damaged.
Protecting your Data There are two ways to avoid losing data you store on disk: you can make backup copies and you tan write-protect your diskettes. You need to format new diskettes before you can use them with an operating system. Formatting erases all the data on a diskette and prepares it to receive new data, so be sure to format only new blank diskettes or diskettes that contain data you want to erase. Refer to your MS-DOS (or other operating system) manual for instructions on how to format diskettes.
00 ‘Write-protect notch Figure 3-1. Write-protect notch On a 3Sinch diskette, the write-protect device is a small switch on the lower-right corner on the back, shown in Figure 3-2. To write-protect this diskette, slide the switch down toward the edge of the diskette so there is a hole where the switch used to be. To write to a 3%inch diskette, move the switch up toward the center of the diskette so the hole is covered. Write-protected I Figure 3-2.
Using Two Diskette Drives Operating systems usually expect the computer to have at least two physical disk drives. Normally, MS-DOS recognizes drives A and B for two diskette drives, and C for the hard disk drive. A typical way to use a two-drive system is to load MS-DOS from drive A, run your application software from the same drive, and use drive B to store your data files.
Although it has a lot of storage space, keep only files you use regularly on the hard disk, to ensure you always have plenty of space available. Store your other files on floppy disks. Before you can use an Epson internal hard disk, you must do the following things to prepare it: Use the Setup program on your reference diskette to prepare your system for using a hard disk, and then use the Format Hard Disk program to format the hard disk.
Chapter 4 Installing Option Cards Option cards are accessories that you can install in your Equity II+ to provide extra capabilities. For example, you can add another disk drive or an auto-dial modem. The Equity II+ has six option card slots, so it can hold up to six cards. The parallel and serial interface and floppy disk controller card occupies one slot. If your Equity II+ has a hard disk, a hard disk controller card occupies another slot.
Figure 4-1. Back and side panel screws 3. Turn the main unit around so the front panel faces you. Hold on to the two sides of the cover and carefully pull it straight toward you, away from the back of the computer, as shown in Figure 4-2. The cover fits tightly, so if you have trouble moving it at first, keep pulling it firmly. Figure 4-2.
4. You can separate the sides of the cover from the bottom ledge of the computer by pulling them outward slightly, as shown in Figure 4-3. Figure 4-3. Remodeling the cover 5. When the back edge of the cover is a few inches away from the back panel, you can lift the cover off. Set the cover aside. Installing an Option Card Figure 4-4 shows the six option slots in the Equity II+. Slot 6 contains the parallel and serial interface and floppy disk controller card. Be sure to install the video card in slot 5.
Figure 4-4. Option slots 16-bit option car Figure 4-5.
Except for the video card, it does not matter which slot an option card occupies, as long as the card fits in the slot. For example, you can place some 8-bit cards in a 16-bit slot. But if an 8-bit card has an additional skirt along the bottom (which looks like an extra long connector), it must go in an 8-bit slot. The video card must be installed in slot 5. See Figure 4-4 to see how the slots are numbered. Also, some other cards must be installed in a specific slot.
2. Unpack the option card and adjust any switches or jumper connections on it if necessary. (For example, a memory expansion card usually contains DIP switches that you need to set. See the option card instructions.) Note: If the option card you are installing requires you to change any of the jumper connections on the Equity II+ main circuit board, memory card, or multi-function card, see Appendix A, “Jumper Settings.
5. Once the connector pins are sitting in the connector slot, push the card downward firmly (but carefully) to fully insert it. If the card does not go in smoothly, do not force it-pull it all the way out and try again, keeping it straight. 6. Secure the adapter plate on the end of the card to the back of the computer with the retaining screw. Removing an Option Card To remove an option card, follow the same basic procedure you used to install it.
Post-installation Setup After you install an option card (and replace the main unit’s cover and reconnect the power cord and peripherals), you may need to run the Setup program on the reference diskette to update the configuration information. For example, if you add a hard disk, you need to tell the computer that it has the additional drive. See the Diagnostics section of this manual for instructions. You may also need to add some commands in the configuration file on your system disk.
Chapter 5 Troubleshooting You should not encounter any serious difficulties as you set up and use your Equity II+. But if anything out of the ordinary happens, refer to this chapter. Usually, such a situation requires nothing more than adjusting a cable connection, repeating a software procedure, or resetting the computer. You can use the suggestions here to solve most problems you may encounter. If the recommended solution does not work, consult an Epson dealer about servicing the computer.
Use the controls on the monitor to turn up the brightness and contrast. Remove any diskettes, then turn off the power switches on the monitor and the main unit. Check that the monitor’s power cable is securely connected to the electrical outlet and that the monitor cable is properly connected to both the monitor and the main unit. Turn both power switches back on. Turn off the power switches on both the main unit and the monitor. Then check the electrical outlet for power.
2. Have you inserted the right type of diskette? The diskette type is normally shown on the manufacturer’s label. See ‘Choosing Diskettes for the Equity II+ ” and “Drive and diskette incompatibilities” in Chapter 3. 3. Is the diskette write-protected? There may be a write-protect tab over the notch on the side of the diskette (5%inch) or the write-protect switch may be set (on a 3%inch diskette).
Printer Problems Your printer manual describes methods to solve most printer problems. If your printer does not work correctly right after you install it, make sure the printer has power and is properly connected to the computer. The printer manual tells you how to connect your printer. If you have printing problems, check the printer manual for the printer’s DIP switch settings. The DIP switches on a printer help it communicate properly with the computer. Be sure your software is set up for your printer.
Appendix A Jumper Settings This appendix describes how to set the jumpers inside the Equity II+ if you install optional devices that require different jumper settings in the main unit. It is best if your dealer installs the option and makes all the necessary adjustments when you buy it. If you decide to do it yourself, be very careful when you follow the procedures in this appendix.
WARNING: The jumpers on these cards are preset at the factory in default positions. Do not change any of them unless you are sure the option card you are installing requires different settings. If you have any doubts, ask your Epson dealer. The procedure for changing a jumper setting is given first, then the jumper functions and locations for each card are described separately. All the instructions assume you have already removed the cover from the main unit.
EPROM size. You can change the EPROM size jumper if you install a different size of EPROM. 0 In all cases, make sure you need to alter the jumper settings for the option you are installing before you change anything. Table A-l shows the functions for the jumpers on the memory card. Table A-1.
2. Lift the card gently out of the computer, taking care not to catch it on any cables inside the computer. Set it on a soft surface, such as a towel, with the component side facing up. Figure A-4 shows the locations of the three jumpers. Refer to Table A-l above to set them as needed. Figure A-4. Memory card jumpers When you finish setting the jumpers, replace the memory card in the computer and secure it with the retaining screw.
Math coprocessor clock speed. If you or your dealer installs an 80287 math coprocessor, you may need to set the jumpers for a different clock speed. The jumpers determine the speed of the coprocessor. l As it is easy to damage a math coprocessor, you should have your dealer install it for you. In addition to checking the jumper settings, you or the dealer should also use the diagnostics’ Setup program to change the settings in the CMOS RAM, and use the System Diagnostics program to test the coprocessor.
Figure A-5. Main circuit board jumpers Multi-function Card Jumpers The jumpers on the multi-function card control the parallel port address and the serial port address. You normally address the parallel and serial ports in the computer as the primary ports (LPT1 and COM1). However, if you install an additional parallel or serial port and want it to be the primary port, you need to change the jumpers on the multi-function card so the built-in port becomes secondary (JPT2 and COM2).
Table A-4 shows the jumpers on the multi-function card that control the serial port. Table A-4. Multi-function card jumper settings for serial port 5 Jumpert3number 9 A A B l A B A B Function Enable built-in port as primary * Enable built-in port as secondary Disable built-in port Default setting To access the multi-function card jumpers, you need to remove the card from the computer: 1. Unplug the disk drive cable from the card as shown in Figure A-6.
Figure A-7. Removing multi-function card retaining screw 3. Remove the card from the slot (pull it straight up) and set it on a soft surface with the components facing up. Figure A-8 shows where the jumpers are located. Change them as needed and then reverse the three steps above to reinstall it. Figure A-8.

Diagnostics
Introduction This special section of your manual describes how to initialize your Epson® system after it is assembled, and how to test the condition of your computer and peripherals. To set up and test your system, you use a group of programs called diagnostics on the reference diskette. Depending on the system you purchased, these programs and some of the screen displays may vary.
ROMBIOS Displays the computer’s ROM BIOS version number. SYSTAT Displays the system parameters. These commands are easy to use. The ROMBIOS command displays the ROM BIOS version number for your computer. When you type ROMBIOS and press Enter, you see a message similar to this: ROM BIOS Version 2.00 The SYSTAT command displays the system information you supply when you run the Setup program. After you run Setup, you can type SYSTAT and press Enter to display the system parameters.
The OPERATION MENU After the power-on self test completes successfully, the diagnostics programs start. Depending on the exact system you purchased, these programs and certain screen displays may vary.
l If you have run a diagnostics program, you see this selection: pl - Exit and reset In this case, when you press 0 and Enter, the system is reset. Before selecting this option, remove the reference diskette from drive A and insert your startup diskette so the system can boot normally. To boot from your hard disk, be sure to remove the diskette from drive A. This manual describes each menu item in the order it appears on the OPERATION MENU.
Chapter 1 Setting Up the System This chapter describes how to use the Setup program to make changes to the list of equipment maintained by the computer. You can select Setup from the OPERATION MENU, or you can execute the MS-DOS SETUP command. You must run Setup when you use your computer for the first time. You also need to use Setup if you change your system configuration by installing or removing optional devices, or if your system has a real-time clock and you want to alter the date or time.
You can exit a submenu in one of the following ways: To exit the submenu without making any changes, press t until the cursor block returns to the main menu, or simply press ESC. This cancels any changes you just made to the configuration. l l To set your changes, press 1 to highlight ** SAVE SETTINGS ** and then press Enter. When you exit Setup, the computer writes the changes to CMOS RAM and reboots using the new settings.
Note: If memory on an option board overlaps the computer’s main memory, you must disable that part of memory-either on the option board or on the built-in memory board. To reduce the amount of main memory, you must use the Main option (of this program) and also change a jumper on the built-in memory board. You can find instructions for changing the jumper settings in your User’s Guide. To change the amount of memory, follow these steps: 1.
Using a Different Type of Display Use the Display option if you change the monitor or video card you are using with your computer. The Display setting in CMOS RAM controls the amount of memory used for storing the image on your monitor screen. Note: Make sure that the monitor switch on the front panel or the DIP switch inside the main unit is set correctly for the type of monitor you are using. See your User’s Guide for instructions. To change the display type, follow these steps: 1.
l l If you have a composite color monitor, such as a color television with a video input, try selecting Color/graph 80. If resolution is poor, run Setup again and select Color/graph 40. If you have any other combination of monitor and video card, consult the documentation supplied with your video card. 3. Press 1 or t to move to the appropriate option and press Enter. 4. Now save your settings, and return to the main menu.
Changing Disk Drives Use the Mass storage option if you install an additional floppy or hard disk drive, or if you remove an existing drive and replace it with another type. Follow these steps: 1. On the main menu, press 1 to move the cursor to Mass storage and press Enter. You see a menu like this: ** SAVE SETTINGS ** Press 1 to move the cursor to the drive you want to change. 2. To change a floppy disk drive, position the cursor block to Drive A or Drive B and press Enter.
Setting the Real-time Clock If your system has a real-time clock, it automatically keeps track of the time and date. This kind of clock is backed up by a battery so it keeps running even while the computer is turned off. The MS-DOS TIME and DATE commands, as well as many software packages, display the time and date held in the clock, but they cannot make permanent changes to the time and date settings. Use the Real-time clock option if you need to change the time and date permanently.
3. To set the date, move the cursor to Date and press Enter. You see: Enter the date in the exact form shown in the box, using two digits for the month and the day; the program automatically inserts the dashes. When the date is correct, press Enter. If you enter an invalid date, the computer beeps, and the date does not change. 4. 1-8 When both the time and date are correct, press t to return to the main menu to change other settings.
Chapter 2 Formatting a Hard Disk This chapter describes how you use diagnostics to check or format a hard disk drive after installation. You can also use the MS-DOS command HDFMTALL. Formatting a hard disk destroys all data on the hard disk, in all partitions, so use this program with extreme care. When you install a hard disk drive, run the Setup program to identify the hard disk. Then, select the Format hard disk program, option 2 on the OPERATION MENU. This program offers several formatting options.
The first two options format a hard disk. Normally you use option 1, Conditional format (Normal). This option automatically locates any tracks that are flagged by the manufacturer and marks them so that they are never used. Option 2, Unconditional format, locates any tracks that are flagged as bad, and then allows you to edit the list of bad tracks. The other two options test a hard disk for problems. Use option 3, Destructive surface analysis, to test the entire disk and update the bad track table.
The program starts to scan the disk to find all tracks flagged as bad, starting from the innermost cylinder of the disk. During the scan, you see the number of the cylinder the program is currently checking. For example, if you have a hard disk, the first messages you see are: Format Hard Disk Scanning for flagged bad tracks... Current cylinder is nnn When the scan is complete, the program displays information about the condition of the disk.
If you continue with formatting, you see: Format started. Current cylinder is xxxx When formatting is complete, any bad tracks are flagged, and you see a series of messages like these: Format finished. Flagging bad tracks... Cylinder is xxxx, head is yy Format completed. Press ENTER to return to the menu. Flagged tracks are identified by xxxx and yy. At this point, press Enter to return to the HARD DISK FORMAT MENU.
Unconditional Format Use this option to format your hard disk when you want to enter the list of bad tracks before formatting begins. The main difference between unconditional and conditional formatting is the way in which bad tracks are identified. With the unconditional format, you must enter the list of bad tracks before formatting begins. To start the Unconditional format routine, press 2 and then Enter.
Some of the messages change if the table is full or empty. However, the way that you add a bad track or make a correction is the same. To add a bad track, follow these steps: 1. Press A. You see this prompt: Enter cylinder number (1 - xxxx): 2. Type the number of the cylinder containing the missing bad track, and press Enter. You see this prompt: Enter head number (0 - yy) : 3. Type the head number for the bad track, and press Enter.
WARNING: If any errors occur during this check, all data on the track that produces the error is destroyed. For this reason, if you think that an unflagged bad track is causing trouble, first run option 4, Non-destructive surface analysis, to check the disk surface. This test operates by a complex process of writing, reading, and verifying information on every track of the hard disk, except for tracks that are already flagged as bad tracks. To start the test, press 3 and then Enter.
To flag the error tracks as bad, press Y and Enter. You then see a list of the tracks as they are flagged. You see these messages: Flagging bad tracks... Cylinder is 237, head is 2 Press ENTER to return to the menu. Press Enter to return to the HARD DISK FORMAT MENU. Non-destructive Surface Analysis The Non-destructive surface analysis is slightly simpler than the Destructive surface analysis described in the previous section.
Chapter 3 Formatting a Diskette This chapter briefly describes how, you format a diskette. Normally, you format a diskette using the MS-DOS FORMAT command. However, if you are running diagnostics and decide to test your floppy drives (which requires a formatted diskette), you can select option 3, Format diskette, from the OPERATION MENU. This option is included with the diagnostics for convenience only; it lets you format a double-density diskette without exiting diagnostics.
If drive A is a 1.2MB drive and you format a double-density diskette, you see this warning message: WARNING! This disk is not suitable for testing a 360, KB drive. Press Enter to return to the menu. For a complete description of the FORMAT command, refer to the MS-DOS manual.
Chapter 4 Performing System Diagnostics This chapter describes how to check the operation of the main unit and peripheral devices of your system. You check these devices using System diagnostics, option 4 on the OPERATION MENU. Always run diagnostics after adding or removing optional devices, or if you are unsure whether a device is performing correctly. You should also run these tests after moving your computer from one place to another, and after you replace the internal battery.
Using the System Diagnostics Program When you start the System diagnostics, the computer checks: l The setting of the monitor switch (for monochrome or color) l The positions of the internal jumpers l The peripheral devices that are connected to the system. After these items are checked, you see a list of the devices available for testing. This list includes only the devices that are installed in the system.
Modifying the DEVICE LIST If an installed device is missing from the DEVICE LIST, it is important that you add it to the list and test it carefully. In response to this prompt: Is the DEVICE LIST correct (Y/N)? press N followed by Enter. You see a new menu: Modify DEVICE LIST l - Add devices 2 - Delete devices 0 - Exit Enter selection number: To add a device to the list, press 1 and then Enter. The program displays a list of other devices that are not currently included in the DEVICE LIST.
Type the number of the item you wish to add and press Enter. You can add as many devices as necessary. When the DEVICE LIST is complete, press 0 followed by Enter. Note: Even if you have both monochrome and color monitor video cards installed, you can only test the monitor that is currently selected. You select the monitor either with the monitor switch on the front panel or a DIP switch inside the main unit. To remove a device from the list, press 2 and Enter.
reliability testing of essential functions only; in most cases, running a test only once is sufficient. To perform the test once, press 1 and Enter. The program then displays a submenu of more detailed tests for the device you are checking. To perform the test multiple times, press 2 and Enter. You see this prompt: Terminate checking if an error detected (Y/N)? Press Y and Enter to terminate checking if the device produces an error, or press N and Enter to repeat the tests regardless of an error.
The program continues after an error in one of the following ways: It returns to the DEVICE LIST, or l If you are running multiple tests and are not terminating on an error, the program repeats the test that caused the error. l The remainder of this chapter describes the tests you can run on the system’s internal devices and on the optional devices installed on your computer. The program displays the titIe of each check on the screen.
For this check, the program writes specific data into memory and then reads it back. The data is written and read in blocks of 64KB. A parity check is also made on each block. A memory count displays after each block tests without error. After the program checks the last block, you see a message like: 000640 KB 0K If an error occurs, make a copy or a printout of the error code and message, and contact your dealer or Epson for customer service.
After you select a keyboard layout, the program displays the layout on the screen. When you press a key on the keyboard, the corresponding character displays on the screen. If the character on the screen and the key you press do not match, there is a problem with your keyboard. Test each key. The status of the Num Lock, Caps Lock, and Scroll Lock indicators is shown on the upper right side of the keyboard layout.
You can select the individual checks from this menu: MONOCHROME ADAPTER AND CRT CHECK MENU 1 3’ 4 5 6 - Monochrome adapter check Attribute check Character set check Video check Sync check Run all above checks 0 - Exit Enter selection number: If an error occurs during any of these tests, record the error code and message, or print them out. Then contact your dealer or Epson for customer service. Monochrome adapter check To check the monochrome adapter, press 1 and then Enter.
If the display attributes are not correct, adjust the brightness and contrast on your display monitor. If they are still incorrect, press N and Enter. Character set check To check your character set, press 3 and then Enter. The character fonts that are included in the internal character generator display on your screen.
Sync check This test is provided for service purposes only. If you accidentally select this option, press any key to end the test. Run all above checks To run all the tests on the menu in sequence, press 6 and Enter. When you choose this option, all checks for the monochrome adapter and CRT are performed automatically in sequential order. Although you do not start each test, you must still supply the appropriate responses to progress from one test to the next. Press any key to return to the menu.
If an error occurs during any of these tests, record the error code and message, or print them out. Then contact your dealer or Epson for customer service. Color graphics adapter check To check the color graphics adapter, press 1 and then Enter. The computer checks the video RAM (display memory) on the display adapter by writing test data to memory, and then reading it back and comparing it to the written data. The computer also tests the video enable signal of the display controller chip.
After checking the character fonts, respond to the prompt: Is the display correct (Y/N)? If the characters match the illustration, press Y and then Enter. If you find a problem with the characters on the screen, press N and Enter to display the error message. 40-column character set check To check your 40-column character set, press 4 and then Enter. The character fonts that are included in the internal character generator display on your screen.
320x200 graphics mode check To check your 320x200 graphics mode, press 5 and then Enter. The screen displays three colored squares-light green, brown, and red-against a cyan background. These four colors are Color Set 0. If they are correct, press Y and then Enter. The same pattern displays again; this time the squares are cyan, white, and magenta, and the background is red. These colors are called Color Set 1. If these are also correct, press Y and then Enter to end the test.
Screen paging check To check the screen paging of your monitor, press 7 and Enter. The video RAM on the color graphics adapter is divided into eight independent display pages. This test checks the eight pages by first filling all eight with a number corresponding to the page, and then displaying each page in turn. You see this pattern for screen 0: Once you examine this screen, press any key to display the next page. The eight pages, numbered 0 to 7, display sequentially.
If you do not have a light pen attached, press N and Enter. To begin the test, press Y and Enter. You see this prompt: PLACE LIGHT PEN ON CENTER OF WHITE BLOCK Touch the center of the white block on the screen with the light pen. When the light pen is correctly positioned, the block moves to another part of the screen for a second test. After three successful tests, the check ends.
Run all above checks To run all the tests on the menu in sequence, press 11 and Enter. When you choose this option, all checks for the color adapter and CRT are performed automatically in sequential order. Although you do not start each test, you must still supply the appropriate responses to progress from one test to the next. Floppy Disk Drives and Controller Check Use this option to test the performance of the floppy disk drives installed in your computer.
Before any checks are performed, the program determines the number of floppy disk drives installed in your computer. If you have more than one drive, you see this prompt each time you select a test: Check which drive (A/B)? Press A or B and then Enter. If any errors occur, record the error code and message and contact your dealer. Always have the floppy disk drive serviced by your dealer. Sequential seek check This test checks the ability of the read/write heads to locate any part of the diskette.
If you have only one floppy disk drive, you see a prompt to remove the diagnostics diskette and insert a blank diskette before running the test. You see these messages: Use only a formatted blank diskette for this test. Any data present may be erased. If using drive A, remove your Diagnostics Disk. Enter Y to start this check. Enter N to return to the menu. Make sure the blank diskette you prepared is in drive A, then press Y and Enter.
Select option 5 from the menu to start this test. First the program checks the selected drive type; if the drive is a 360KB drive, you see these messages: Drive d is a 360KB drive. DISK CHANGE is not allowed with this type of drive. Press ENTER to return to the menu. d represents the name of the drive you selected. When you run the test for a 1.2MB or 720KB (3Y2”) drive, you see this prompt: Remove the disk from drive d. Release the disk drive lock, and remove the disk.
Parallel Port (Printer Interface) Check Use this option to test the operation of the primary parallel printer port. To perform the test, you must insert a special loop-back connector into the parallel port so that the computer can check individual pins of the port. Contact your dealer if you need a loop-back connector. Note that a different connector is required to test the serial port. When you select option 9 from the DEVICE LIST, you see these prompts: Attach loop-back connector to parallel port.
When you select option 11 from the DEVICE LIST, you see these prompts: Attach loop-back connector to serial port. Enter Y to start this check when connector is attached, or Enter N to return to the menu. Insert the loop-back connector. Then press Y and Enter to start the check. First, the computer checks the serial port control lines to see that they are able to change from high to low and vice versa. No messages display during this part of the test unless an error occurs.
Alternate Serial Port Check Use this option to test the functions of an additional serial communications (RS-232C) port. To perform the test you must insert a special loop-back connector into the alternate serial port so that the computer can check individual pins of the port. This test is identical to the check for the primary serial port. For more details, refer to the description of the Serial Port (RS-232C) Check.
care with certain software. The bit-image data is sent to the printer using a command (ESCK) compatible with Epson and IBM® printers. If this pattern is printed correctly, you can use the MS-DOS GRAPHICS program to print out copies of graphics screens. Note: Even if the test runs only for a short time, your printer may store many characters in its buffer. To stop printing, turn the printer off-line.
Seek check This test checks the ability of the read/write heads to locate any part of the hard disk. This action by a read/write head is called a seek. During this test, each head seeks each cylinder of the disk in sequence, starting from the center. Select option 1 from the menu to start this test. The program displays the number of each cylinder it finds. For example, with a hard disk, the first message you see is: Current cylinder is nnn The cylinder number counts down to 0.
If this analysis shows no other problems with the disk, follow these steps: 1. Back up all the files on your hard disk. 2. Re-format the disk using option 2, Format hard disk, on the OPERATION MENU. 3. Re-create the MS-DOS partition with FDISK and format it with SELECT. (See your MS-DOS manual.) 4. Restore your files. Head select check This test checks whether each head of the hard disk drive can be selected correctly. If both heads are checked without an error, the program returns to the menu.
Read, verify check This test reads and verifies data from all tracks of the disk, checking each cylinder and using both heads. Select option 5 from the menu to start this test. The program displays the number of each cylinder it finds. For example, with a hard disk, the first message you see is: Current cylinder is nnn The cylinder number counts down to 0. At the end of the test, you see a table of the results of the test. For example, for a hard disk with no bad tracks, you see: BAD TRACKS . . . . . . . .

Chapter 5 Moving the Hard Disk This chapter describes the procedure you use when you plan to move your computer. Even if you are moving the computer only a short distance, use option 5, Prepare hard disk for moving, to prevent damage to the hard disk. This program moves the read/write heads of each installed hard disk drive away from the disk surfaces and locks them securely in position.

Appendix C Power-on Diagnostics The built-in memory (ROM) of your computer contains a series of diagnostics programs. These programs are run automatically by the system every time you turn on the power. The diagnostics programs check the internal devices such as ROM, RAM, keyboard controller, timer, video controller, floppy disk driver, and hard disk controller. When you turn on the power, your system performs the tests described in this appendix.
where x is a number from 1 to 8 that represents the specific LSI circuit in which the error is found. Your service dealer needs this information to find and correct the problem. If an I/O or checksum error occurs, you see this message: xxxx0 ROM error where xxxx is the number of the segment of the bad I/O ROM. Clock and CMOS RAM Check When the system device check is completed successfully, the computer checks the timer and CMOS RAM.

If there are faulty RAM chips in your system, you see one of these messages: 202-Memory address error 203-Memory address error If an I/O or parity error occurs, you see one of these messages: Parity check 1 Parity check 2 The program also displays the number of the segment causing the problem.
Optional RAM Check If any additional memory (expansion RAM) is installed, the computer then checks that RAM for any malfunction. Floppy Disk Drive Seek Check The computer checks its floppy disk drives by searching the read/write heads for any malfunction. If any seek errors are found, you see this message: 601-Diskette error If this error occurs, confirm that the system diskette is inserted into drive A. If this number still appears after you insert the diskette, the disk drive must be repaired.
