A/UX (from Apple Unix) was Apple Computer's implementation of the Unix operating system for some of their Macintosh computers. The later versions of A/UX ran on the Macintosh II, Quadra and Centris series of machines as well as the SE/30. A/UX was first released in 1988, with the final version (3.1.1) released in 1995. A/UX required a 68k-based Macintosh with an FPU and a paged memory management unit (PMMU).
The operating system was based on UNIX System V Release 2.2, with some additional features from System V Releases 3 and 4, and 4.2 and 4.3 BSD. It was POSIX and System V Interface Definition (SVID) compliant and included TCP/IP networking from version 2 onward. There were rumors of a later version using OSF/1 as its primary code base, but this system was never released to the public, if it even existed.

While it sure is better than 1.1.1 or 0.7, version 2 feels more like what A/UX should be. Although this version revolves around system 6.

And compared to a stock system 6, well A/UX is so much nicer, having a real UNIX underneath, in the same way OS X has Mach/BSD Unix underneath.

Such a shame Apple didn't run further with A/UX, and insisted on releasing braindead models that couldn't run it. At least the acquisition of NeXT and the release of OS X vindicates the A/UX design.

A/UX 2.0 is on here. But an installation CD is still needed. And a working FPU and PMMU emulation in Mini vMac.
