– Parity (36 bit) or Non-Parity (32 bit) memory SIMMs.
– Memory speed of 60 nanoseconds (ns).
– Tin-lead contacts.
– Fast page mode or extended data out (EDO).
– Dynamic Random Access Memory (DRAM).
One, 168-pin Gold, EDO, 60 ns, Parity or Non-Parity DIMM module.
Depending on model, 7 MB, 14 MB, 16 MB, or 24 MB of system
memory is supplied. Maximum system board memory is 128 MB. Refer
