 TOPIC -----------------------------------------------------------

 This article describes the Apple IIGS Memory Expansion Card.

 DISCUSSION ------------------------------------------------------

 Overview
 --------
 The Apple IIGS Memory Expansion Card gives your computer the internal memory
 needed to run sophisticated applications, and gives complete access to the
 advanced capabilities of the Apple IIGS.

 Although the 256K of RAM resident in the computer already lets you keep large
 documents and many applications close at hand, the Memory Expansion Card will
 hold even larger files and programs, further reducing time-consuming disk
 access.

 The Apple IIGS Memory Expansion Card adds up to a full megabyte (1MB) of RAM
 to the computer, in 256K increments. This means the total RAM in your system
 can be as high as 1.25MB with ROM 01, or 2MB with ROM 03. You can configure
 and install the card yourself, and increase its capacity at any time.


 System Requirements
 -------------------
 To use the Apple IIGS Memory Expansion Card, you need an Apple IIGS or an
 Apple IIe with the Apple IIGS Upgrade installed. (This card is not compatible
 with other computers in the Apple II family.)
