lntroduclion The Apple@ IIcs Memory Expansion Card adds 256K, 512K, or 1 megabyte of memory to the Z56x of RAM built into the Apple IIGS. The amount of memory it adds depends on whether you irutall the card straight out of the box or upgrade itto 512K or 1 megabyte. ce Addtng nenory: You can upgrade the card yourself, by gening one or more Apple 256K memory expansion kits, or you can have your authorized Apple dealer upgrade the card for you. Each kit adds 256K to the memory on the card.
Rodio ond lelevision interference The equipment described in this manual generates and uses radiofrequenry energy. If it is not installed and used properly--+hat is, in strict accordance with our instructions-it may cause interference with radio and television reception. This equipment has been tested and complies with the limits for a Class B computing device in accordance with the specifications in Subpart J, Part L5, of FCC rules.
Chopter I lnslolling the Cqrd Here's how you install the Apple IIGS Memory Expansion card in the Apple IIGS. If you have one or more memory expansion kits, you should add those chips to the card before installing the card in the Apple IIGS. Turn to Chapter 3 for upgrade instructions. lmporlont lf your computer's power is on, furn it off ond woit of leost 30 seconds before instolling or removing the memory exponsion cord. 1.
4. Touch the power supply case inside the computer to discharge any static electricity that may be on your clothes or body. (See Figure 1-2.) 5 Put the card in the memory expansion slot as shown in Figure 1-J. You'll have to exert some pressure to get the card in the slot. But don't wiggle the card from side to side in your efforts to insert it. Rock it forward and back until it's firmly seated in the slot. Eb.. .'zl 1r" a "t.
Chopter 2 Memory Exponsion Cord os RAM Disk Many applications designed especially for the Apple IIGS take advantage of the extra memory on a memory expansion card automatically. In some grses you can't use the application-or can't take advantzge of all the application's features-without adding a memory expansion card. If you got the card specifically to use those kinds of applications, you can stop reading right here. Another way you c:tn use the memory on the card is as a RAM disk.
Setting RAM disk size Ihe Apple iles Ownels Guide exploins how to chonge Control Ponel settings. Before you can use the memory on the card as a RAM disk, you need to use the Control Panel Program to tell the computer how much of the memory on the card you want to set aside for use as a RAM disk. (See Figure 2-1.
In the example shown in Figure 2-2, there is 512K available on the card. The minimum RAM disk size has been designated as 255K, and the maximum RAM disk size has been designated as 320K. That means that applications will have a minimum of 192K (5tZ -320) to use and can use as much as 256K (StZ - 255) tf you aren't akeady using that memory as a RAM disk.
Addressing the RAM disk Many applications will ask for the locarion of your RAM disk by slot and drive number. A memory expansion card used as a RAM disk appears to be in slot 5, just as a 3.5-inch drive connected to the disk drive port appears to be in slot 5. The following rules and examples explain how to figure out where your RAM disk is in relation to your 3.5-inch drives. tules 1. Your startup device is always drive 1. @emember, you can change the starttrp device by using the Control Panel program.
Using the RAM disk To copy and run applications from the RAM disk, you need to: 1. (Optional) Format the RAM disk. This is necessary only if you plan to use the RAM disk as your startup device. The RAM disk is preformatted at startup for storing applications and documents. 2. Copy applications to the RAM disk. 3. (Optional) Make the RAM disk your startup device by using the Control Panel Program. 4. Start up your application from the RAM disk.

Most PToDOS opplicotlons put you into BASIC ofter you choose the Quii option fiom the Moin Menu, If the RAM disk is not your startup device, or if you have more than one application on the RAM disk, get into the BASIC programming environment and type -/RAM5/f ile (where RAM5 is the name of your RAM disk and f ile is the name of your application's system file). The system file is the file with the name ending in . SYSTEM. (For example, to start up Apple\(orks from the RAM disk, you'd rype -/RAM5 /APLWoRKS .
Chopter 3 Upgroding to 512K or to I Megobyte The Apple IIGS Memory Expansion Card comes with 255K. You can upgrade itto 512K by gening an upgrade kit or to 1 megabyte by getting three upgrade kits. (Each upgrade kit adds z56x of RAM to ttre card.) It's not a good idea to upgrade the card to Z6gr because some applications have trouble dealing with that memory configuration. The memory expansion kit comes with 8 RAM chips You'Il also need the jumper blocks that came with the card.

Figure 3-3 lnstollchips Figure 3-4 Rollo chip r Align all of the pins on the chip with the holes in the card so you don't inadvertently bend or break a pin in the process of installing the chip. Do not try to insert a chip with bent pins. Ask your dealer for a replacement chip.
