Amiga 3000UX

The Commodore Amiga 3000UX is a model of the Amiga computer family that was released with Amiga Unix, a full port of AT&T Unix System V Release 4 (SVR4), installed along with AmigaOS. The system is otherwise equivalent to the standard A3000, once a right-click initiates a boot to Kickstart (Amiga's kernel).
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 their high-end Sun workstations. That this offer was declined was one of the many management decisions that led to the popular belief that the Amiga platform would have been a real success story but for Commodore management.
It is possible that Commodore (or a third party) repurposed A3000UX machines for standard AmigaOS, as some standard A3000 models have been found with labeling suggesting they were originally to be sold as A3000UX machines.
