I have one meg's worth 256K SIMMS (four of them) that came out of my Mac (150ns) Can I use these for memory upgrade in my 286-12?? If these are too slow, can I use them as some sort of RAM Disk?? Thanks

Mac memory will not work on IBM PC's at all, no matter what the speed. Memory in the macintosh do not utilitize partiy check SIMMS. Macintosh memory are of the configuration 1x8 (an example) whereas its equivalent on the PC would be 1x9 since you have that extra partiy checking "bit". As far as I know, there would be no applications on any typical IBM-PC setup (ie video card RAM) set-up that could utilize the Mac RAM. Might be wise to just sell it to another Mac owner and use the money to by some compatible RAM. I'm no expert on this so I could be very wrong. Just trying to help :).

Saurabh: Don't try doing it. I know that the SIMMS will not work in a PC (Mac SIMMs are 256k x 8 while the corresponding PC SIMM would be 256k x 9). PC SIMMs check for parity while Mac SIMMs don't -- Ashok Aiyar axa12@po.cwru.edu aiyar@cwbio.bioc.cwru.edu
