Apple Macintosh II

Personal computer model, first of the Macintosh II series in the Apple
Macintosh line. (Not to be confused with the Apple II family of
non-Macintosh computers.)

The Apple Macintosh II was the first "modular" Macintosh model, so called
because it came in a standard desktop case. All previous Macintosh computers
used an all-in-one design with a built-in black-and-white monitor. The Mac
II allowed Macintosh users a choice of larger displays, color displays, and
even multiple displays.

Introduced March 02, 1987, the Mac II featured a Motorola 68020 processor
operating at 16 MHz teamed with a Motorola 68881 floating-point coprocessor.
Standard memory was 1 megabyte, expandable to 68 megabytes. A 40 megabyte
internal hard disk was optional, as was a second internal 800 kilobyte
3.5-inch floppy disk drive. Six NuBus slots were available for expansion.

The Macintosh II was followed by a series of confusingly-named modular Macs
including the Macintosh IIx and Macintosh IIfx, all of which used the
Motorola 68030 processor.
