Building on the success of the Mac
IIcx, the IIci offered the 65% more power in the same
compact case. A new feature was on-board video. The
advantage was that users no longer needed to buy a video
card; the drawback was that internal video used RAM from
the motherboard, slowing the computer. Adding a video
card was a popular way to increase performance (up to
30%!); another boost came from adding a level 2 (L2)
cache. This proved so popular, Apple eventually made a
32KB cache standard.
The IIci was the first Mac with "clean" ROMs, allowing
32-bit operation without MODE 32.
