Macintosh IIfx

Compared with the Macintosh IIx, this model runs its 68030, 68882 and system bus at 40 MHz instead of 16 MHz, and it adds a 32 KB level 2 cache. Two dedicated input/output processors handle the floppy drive, sound, serial ports and ADB. It needs special 64-pin SIMMs that other Macs of the time did not use. The six-slot case did not change.
