At last, here's the summary to my questions about the 8-UP: [ The 8-UP from MicroBotics: anybody see this beastie? And more [importantly, what kind of SIMMs does it need? Can it use the Mac's 256K SIMMs? I've had one response from Rodger Anderson: >Yes, I have one. I am quite pleased with it, but then, what should one >expect form a memory board? It does its job just fine. As far as SIMMS >go, I had the same questions that you do. I guess there aren't as many >different kind of SIMMS as I thought, because the ones I had (1 MEG's) >worked just fine. 256K SIMMS are documented to work also. You have to >install them in pairs. You can use either 8 bit or 9 bit. The extra >bit is just ignored, but I guess the pin-out is the same. The only >possible problem I can think of is that SIMMS come in two connector >styles. The connector that looks like a printed circuit edge connector >is the one you want. They also come with pins, like IC legs. The 9 bits are for the PS2 line, no doubt. I never heard of (or seen) the "legs" type. The major difference between Mac SIMMs is the speed; the Mac+ and SE can use 120ns vs. 100ns for the Mac II. Often the 120ns SIMMs seem to work fine in the Mac II, but you can never really be sure. >So, basicly, you should be able to use any SIMMS. Sounds to me like it can handle the least common denominator which in this case is 120ns. >> The only other question I have is how much did the >> sucker cost and from where. >I bought my 8-Up from my local dealer.
