> A/UX is a discontinued Apple Computer implementation of the Unix
> operating system (current Unix implementation is macOS) for some of
> its Macintosh computers. A/UX requires a 68k-based Macintosh with an
> FPU and a paged memory management unit (PMMU), and various versions
> run on the Macintosh II, SE/30, Quadra and Centris series of
> machines. A/UX was first released in 1988, with the final version of
> 3.1.1 released in 1995.
>
> Described by InfoWorld as "an open systems solution with the
> Macintosh at its heart", the operating system is based on UNIX
> System V Release 2.2. It includes some additional features from
> System V Releases 3 and 4 and BSD versions 4.2 and 4.3. It is POSIX
> and System V Interface Definition (SVID) compliant and includes
> TCP/IP networking from version 2 onward. Having a Unix-compatible,
> POSIX-compliant operating system made it possible for Apple to bid
> for large contracts to supply computers to U.S. federal government
> institutes.
>  [...]
>  The final release of A/UX is version 3.1.1 of 1995. Apple abandoned
> the A/UX platform completely by 1996.
