Powered by a 16MHz Motorola 68030 processor.
Same form factor as the Macintosh IIci though there are some differences between these systems:
- Does not have the cache card option as found in the IIci
- Does not have onboard video and requires a NuBus video card
The IIcx offers three NuBus expansion slots, though one slot will need to be used for a video graphics card as the IIcx does not feature an on-board video port.
