SIMM Installation

By installing SIMMs, you can increase the amount of
memory up to 132MB
There are two SIMM sockets on the system board, and each
can contain one memory module. You can install 1MB, 2MB,
4MB, 8MB, 16MB, 32MB, and 64MB SIMMs. The sockets are
labeled on the system board.
The following table shows the recommended SIMM
configurations. Do not install SIMMs in any other
configuration.

Use only tin-plated, 32-bit, 72-pin, fast-page mode SIMMs
that operate at an access speed of 70ns or faster. Be sure all
the SIMMs operate at the same speed.

Video Memory

You can increase the video memory to 2MB by installing
additional 512KB, 40-pin, SOJ flat pack video DRAM chips.
