The Macintosh II was the first personal computer model of the Macintosh II series and the first Macintosh to support a color display. The 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.
