Atari Corp was doing the same thing around the same time as Commodore was, with their own branded SysV fork. Both were trying to get into the later stages of the workstation market because it was seen as a new revenue source at a time when the "home computer" market was disappearing.

But I distinctly remember an editorial in UnixWorld magazine (yes, we had magazines like that back then you could buy in like... a drug store...) with the headline "Up from toyland" talking about the Atari TT030 + SysV. Not exactly flattering.

The reality is by 1992, 93, 94 the workstation market was already being heavily disrupted by Linux (or other x86 *nix/BSD) on 386/486. The 68k architecture wasn't compelling anymore (despite being awesome), as Motorola was already pulling the rug out from under it.

And, yeah, many people just ran NetBSD on their Atari TTs or Falcon030s anyways.

I imagine any home computers manufacturer looked at the workstation 68000 machines like Sun and said "we have the same CPU, if we have a Unix we can market our computers as workstations at a fraction of the cost". You also had Apple release A/UX for their 68k Macs.
