We've got some 256K SIMMs that were taken out of our LaserWriter II when its memory was upgraded. Can these SIMMs be used in a Mac II the same way that other 256K SIMMs can? If not, are they good for anything at all? -- Mark H.

I tried putting some extra Mac II SIMMs into an LW II NTX and found to my chagrin that they wouldn't fit. I presume the only thing that your spare LW SIMMs are good for is for putting into other LWs. Perhaps there is some good technical reason for this, and for LW SIMMs being 3-6% cheaper than Mac SIMMs?

The LW SIMMs have a separate bit-enable line for each bit of the byte, to speed up OR-to-Memory functions. Maybe they are cheaper because the demand is relatively low :-), since they can't be used other places. Marc Kaufman (kaufman@polya.stanford.edu)
