Macintosh IIci

Introduced: September 1989
Terminated: February 1993

Description

The Macintosh IIci had the same case and three expansion slots as the Macintosh IIcx. The processor chips were improved from 16-bit to 32-bit and the hard drive came in either 40 or 80MB varieties.

The built-in graphics card meant that there was an extra free expansion slot. However, this also meant that the computer’s RAM was now being used to run the graphics.

History

Many of the improvements worth noting in the Macintosh IIci were enhancements at technical and architectural levels. Many of the changes were in preparation for the new operating system software, System 7.
