Only catch is that you'll have to relocate the 256K SIMMs from bank A to bank B and put the 1MB SIMMs in bank a. This works like a charm. This is the same solution as for a Macintosh II, Macintosh IIx, and Macintosh IIcx, except that there's less room inside so you can't use most DIP (read over-size) SIMMs. Stick with SOJ. (Yes, this means that you can't use our own 4MB upgrade in the SE/30 since it uses DIP SIMMs. You have to use two of our 2MB upgrades, which use SOJ chips, or a third party SOJ based solution.) When you buy, just ask for SIMMs that use low-profile or SOJ RAM. -Dave -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Dave Wells, Apple Computer, Inc.
