A/UX

    (Apple's UniX) Apple's first version of
   Unix for Macintosh computers.  A/UX merges the Macintosh
   Finder (GUI) with a Unix core, offering functions from both
   systems.  It will run on some late-model Motorola 68000
   Macs, but not on the Power Mac.

   A/UX is based on AT&T Unix System V.2.2 with numerous
   extensions from V.3, V.4 and BSD 4.2/4.3.  It also provides
   full POSIX compliance.

   A/UX 3.x.x incorporates System 7 for the Macintosh, thus
   supporting the vast majority of Macintosh applications.
   System 7 and Unix are fully integrated under A/UX 3.x.x with
   the Unix file system being seen as a disk drive by the Finder.
