The Apple Macintosh II was launched in 1987 at the same time as the Macintosh SE. It was considered "revolutionary" because, for the first time, the Macintosh was expandable thanks to its internal slots and had colours (the previous Macintoshes all had monochrome displays). The Mac II also marked Apple's entry into the realm of serious computing.

It used a more classic keyboard (which looked like a PC keyboard) and proprietary RGB monitor (see 'Read more' section). The internal SCSI hard disk could be replaced with an 80 MB disk. It could run under A/UX (The Apple version of Unix System V version 2).

The Macintosh II was followed in September 1988 by the Macintosh IIx. The IIx had the same specifications as the Mac II. It used a 68030 CPU and a 68882 FPU instead of the 68020 and the 68881, an 1.44 MB 3.5" floppy drive and removable system ROMs for easier updates.
