The Apple Macintosh II was the first personal computer model of the Macintosh II series in the Apple Macintosh line. Introduced in March, 1987, the Macintosh II was the first "modular" Macintosh model, so called because it came in a horizontal desktop case like many PCs of the time. All previous Macintosh computers used an all-in-one design with a built-in black-and-white CRT.
The Macintosh II introduced space for an internal hard disk (originally 20 MB or 40 MB) and an optional second floppy disk drive. It also was the first Macintosh computer, simultaneously with the Macintosh SE, to use the Apple Desktop Bus (ADB), introduced with the Apple IIGS, for keyboard and mouse interface
Included with the Macintosh II are 9 diskettes which give the user information on installation, printing, disk tools, tidbits and other information about the Macintosh. The Macintosh II was discontinued on January 15, 1990.
