You can install a maximum of four single inline memory modules (SIMMs)
in the computer. The system supports a minimum of 8 MB and a maximum of 128 MB
of memory. Use only tin lead, 72-pin, 60ns Industry Standard EDO, non-parity SIMMs.
Memory modules are installed in two memory banks, Bank 0 and Bank 1. Each
bank supports 4, 8, 16 or 32 MB single or double-density SIMMs. Each bank used, must contain
a pair of SIMMs of the same size and density. For best performance, fill Bank 0 first.
The following table shows some possible SIMM combinations and the total memory size for each combination.
