* If you install SlMMs in both Bank 0 and Bank 1 or Bank 2 and Bank 3, SIMM
types must match.
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.

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.)
