Commodore International did a full port of AT&T Unix System V Release 4 Unix for the Amiga computer family (in addition to the proprietary AmigaOS shipping with these systems by default).

Contrary to the popular belief that Amigas were primarily gaming machines, this port was considered one of the finest Unixes of its time. The Amiga A3000UX model even got the attention of Sun Microsystems, but unfortunately Commodore did not jump at the opportunity.

With the fall of Commodore International, the Amiga Unix vanished into the mists of computer history. While NetBSD and Linux are still available to what is left of the Amiga user base, the commercial Amiga Unix has not been revived.
