Although this could be done by a person with the right tools, I wouldn't recommend it. Find a good dealer somewhere. If you insist on doing it yourself, make sure you have a good set of instructions, including diagrams of which resistors/jumpers need "adjusting". For machines since the Mac SE (including the SE/30, II, IIcx, IIx, and IIci) you do not need to worry about resistors. (The original posting requested info about the IIcx.) For the SE/30, II, IIx, and IIcx: If you wish to upgrade to 5MB of memory, you must place the 1MB SIMMs in bank A and the 256K SIMMs in bank B. Otherwise the machine will think that you have 256K SIMMs in all eight SIMM slots. For the IIci: This is no longer the case. You may put 1MB SIMMs in bank B and leave the 256K SIMMs in bank A. In fact, this is the recommended configuration if you are using the built-in video. -Michael -- Michael Niehaus UUCP: !{iuvax,pur-ee}!bsu-cs!mithomas Apple Student Rep ARPA: mithomas@bsu-cs.bsu.edu Ball State University AppleLink: ST0374 (from UUCP: st0374@applelink.apple.com)
