INTRODUCTION
About The GS-RAM III Card
Memory Expansion--The GS-RAM III allows you
to increase the Random Access Memory (RAM) capacity
of your Apple IIGS. RAM is the memory that can be both
read From and written to--the addressable memory. Many
programs automatically look for and use available RAM to
give them more room to operate (desktop space). Many
programs load themselves into the available RAM at
startup. This greatly increases their performance because
it reduces or eliminates the need to access the relatively
slow mechanical floppy drives. GS-RAM Ill lets you
increase the available system RAM by a maximum of 4
Megabytes (Mb) on the board itself, in increments of 1
Megabyte. This means that IIGS ROM 03 machines (with 1
Megabyte installed on the motherboard) can have a total of
5 Megabytes while the earlier IIGS’s can have a total of 4.5
Megabytes.
6Mb--when you want to expand beyond 4Mb, you can
attach the 2Mb “Piggyback” Expander. It connects directly
to the GS-RAM III and adds its 2Mb to the 4Mb on the GSRAM HI for 6Mb s of memory.
RAM Disks--Use some of the GS-RAM memory to set
up a RAM Disk. A RAM disk acts as an internal, electronic
hard disk giving you super-Fast access to applications that
are copied to it. Loading from and storing to a RAM disk
can be as much as 20 times faster than a conventional disk
drive because it eliminates the mechanical activity
required by a conventional drive.
DMA Support--The GS-RAM III is fully DMA
(Direct Memory Access) compatible. Any device that
requires DMA-style memory can use all the available
memory on GS-RAM III.
Introduction i
AW 3 Expansion Software--with your GS-
RAM, you’ve also received Applied Engineering’s AW 3
Expander software. This program will greatly enhance the
popular AppleWorks integrated software package adding
such features as more Word Processor lines and Data Base
records, an expanded clipboard, Multiple Disk Save and
more.
Also included on the AW 3 Expander is a graphic test for
your GS-RAM III that will tell you which, if any, chips are
bad and will also check for the proper type of chips.
Refer to the AW 3 Expander User’s Manual for complete
information about the disk.
About This Manual
Below is a brief description of what is covered in each
chapter of this manual.
Chapter 1 will take you quickly through the
installation and testing of your GS-RAM III card.
Chapter 2 tells you how to use some of the expanded
memory as a RAM disk. This is a great way to increase
the access speed to different applications.
Chapter 3, as mentioned above, helps you to decide
what chips you will need to expand the memory of
your GS-RAM III card. It also explains how to install
the chips yourself as well as how to return the card
to Applied Engineering for a memory upgrade with
no additional charge for the installation and testing.
Appendices provide you with instructions on what to
do when you encounter a problem that is not covered
in the manual.
We have tried to make this manual as informative,
understandable, and error-free as possible. If you have
any comments or suggestions regarding this manual or
any other if manual, we would be glad to hear from you.
Please address any comments or suggestions to:

CHAPTER ONE
Getting Started
+ Note: If you’re using GS-RAM III with the
RamKeeper, plug it into the front side of the
RamKeeper only.
This chapter tells you how to install and test the GS-RAM
III memory expansion card. Before you install your
memory-expansion card, please be sure you are familiar
with Setting UP Your Apple IIGs and the Apple IIGS
Owner’s Guide. You’ll need to be particularly familiar
with the Control Panel functions as this manual makes
frequent reference to the Control Panel menu.
Installation
1) Turn off the computer.
Leave the computer plugged in but flip the power
switch to the OFF position.
2) Remove the Apple IIGS cover.
Locate the two latches on either side of the backplate.
Push in on the latches while pulling up and back on
the lid.
3) Touch the power supply case.
The case is shown in the illustration below. This will
discharge any static electricity that may be on your
body. Do not skip this step. Static electricity can ruin
chips on the board and in the computer.
4) Remove the memory-expansion card from Its antistatic bag.
Hold the card by the edges, like a photograph. Do not
touch the gold fingers of the card.
5) Check the position of the switches.
The switches are located toward the top left edge of
the card. The position of the switches lets the
computer know how much memory is on the card.
(Refer to following illustration.)
