SIMM Installation
The computer comes with 16MB of RAM standard on two
8MB SIMMs. You can increase the memory up to 128MB
using 4MB, 8MB, 16MB, or 32MB SIMMs. The SIMMs must be
tin-plated, 72-pin, single- or double-sided, fast-page mode or
EDO mode, parity or no-parity type with an access speed of
70ns or faster. Be sure all the SIMMs operate at the same
speed.
The table below lists all the possible SIMM configurations; do
not install SIMMs in any other configuration.
