Just a clarification of the previous posts:
When installing SIMMs, you only need to worry about resistors and/or
jumpers if you are installing the memory in a Mac SE or Mac Plus. 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.
