Mac II
(Mac II) A version of Apple's Macintosh
personal computer, released in March 1987, using the
Motorola 68020 CPU, which runs at a higher clock rate
than the Motorola 68000 used in the original Mac. The Mac
II has a full 32-bit data bus instead of a 16-bit bus. Mac II
models have built-in 40 to 160 megabyte hard disks and can
take up to eight megabytes of RAM (and more as denser memory
chips arive).
The Mac II was the first Macintosh to provide a colour
graphics option, with up to 256 colours on screen at a 640x480
resolution. Mac II models are designed for expandability with
three (Macintosh IIcx) or six (II & IIx) built-in NuBus
expansion slots for additional peripheral and
coprocessor boards.
