I have 4 256k 120 ns simms that came out of a 1040ste. can my brother use these (and possibly 2 more from a mac) to upgrade a 1040st to 2.5 meg? -steve <selick@bucsf.bu.edu>

To get 2.5meg with SIMMs on an ST/Mega, you need a JRI SIMM board (I don't know of anyone else who distributes them in the US, but there may be quite a few in Europe), 2 one-meg SIMMs, and 2 256K SIMMs. You cannot use 10 256K SIMMs and get 2.5meg because of the way things are designed. I would explain the reason to you, but I don't know it either. Just take my word for it. :^D -- Ed Krimen ............................................... ||| Video Production Major, California State University, Chico ||| INTERNET: ekrimen@ecst.csuchico.edu FREENET: al661 / | \ SysOp, Fuji BBS: 916-894-1261 FIDONET: 1:119/4.0
