A model of the Amiga computer family that was released with Commodore Amiga Unix installed instead of AmigaOS.

Amiga Unix was not a Un*x type clone, but a full port of AT&T Unix System V Release 4 Unix. At one point, Sun Microsystems approached Commodore-Amiga Inc. with the offer to produce the A3000UX under license, as a low- to mid-range alternative to the high-end Sun workstations.

That this offer was declined was one of the many "strange" management decisions that led to the popular belief that Amiga would have been a real success story but for the Commodore management.
