Minutiae:
Upgraded four SIMMs at a time.
There are two logic boards for the Macintosh IIci, one with and one without parity. You can identify the parity logic board by the large parity IC installed to the left of the SIMM slots. If you have a parity logic board, be sure to install parity SIMMs for proper operation.
Only later versions of the IIci came with the L2 cache as standard. On earlier models it was an optional extra.
This is the first Macintosh with a 32-bit Processor Direct Slot (PDS). It was also the first machine with 32-bit clean ROMs.
The IIci uses DRAM for video and maps it to Bank A. Always install the lowest density SIMMs in Bank A for best performance.
Serial Port with the phone icon supports synchronous modems, with handshaking on both the output and input.
