Minutiae:

Some customers have reported problems mixing EDO (extended data out) and FPM (fast paged mode) memory in this machine.  NewerRAM therefore recommends using only EDO memory.

Has the Apple Inline Cache Processor Card which has 1 MB of Level 2 inline cache.  Data is moved between processor and cache on a 100 MHz cache bus.

Upgraded with one DIMM at a time.

Can interleave memory for approximately 10-30% faster RAM access.

Serial Port with the phone icon supports synchronous modems, with handshaking on both output and input supported.

Has 4MB ROM and a 1.44MB SuperDrive.
