Ordinary PC-type 72-pin SIMMs should be fine, but I
think you need Fast
Page Mode rather than EDO.
Based on my findings, I've yet to run into a Mac that can't use EDO. Some
require EDO, but so far, all the ones I've played with that are supposed
to use FPM, work just fine with EDO instead. (note: I have never upgraded
an 8100, so for all I know, that could be the one model that really does
care).
Again, this is based on 72 pin SIMMs. It seems that Apple's 72 pin SIMM
requirements were pretty loose compared to their other memory
requirements.
