SIMM Installation
The computer comes with 4 or 8MB of memory using
SIMMs. By installing additional SIMMs, you can increase the
amount of memory up to 128MB.
There are four SIMM sockets on the main system board, and
each can contain one memory module. You can install 1MB,
2MB, 4MB, 8MB, 16MB, and 32MB SIMMs. The sockets are
labeled on the main system board.
The following table shows the recommended SIMM
configurations. Do not install SIMMs in any other
configuration.

Processor Upgrades
*
If you install SlMMs in both Bank 0 and Bank 1 or Bank 2 and Bank 3, SIMM
types must match.
The computer’s processor can be upgraded by replacing the
existing processor with a faster one. The following table lists
supported processors and voltages.
Use only tin-plated, 32-bit, 72-pin, fast-page mode SIMMs
that operate at an access speed of 80ns or faster. Be sure all
the SIMMs operate at the same speed.
Supported processors
Video Memory
The computer comes with 1MB of video memory. You can
increase the video memory to 2MB by installing two 512KB,
40-pin SOJ flat pack video DRAM chips. (You cannot
increase video memory by installing just one chip.)
Hard Disk Drive Types
Video resolutions and colors
Memory
Refresh
Your computer comes with a hard disk auto-sensing feature.
To use it, select one of the drives you have installed from the
Fixed Disk Setup screen. On the screen that appears for that
drive, press Enter to select the Autotype Fixed Disk
option. The system detects the type of hard disk drive, fills in
the drive’s parameters, and sets the remaining options on the
screen.
