Neat. This is the first time I've heard of this UNIX from Commodore.
I'd heard of Amiga UNIX, which ran on the A3000 and A2000s with the
appropriate 68020(+MMU) or 030 upgrades, and their failed CBM 900
project, which was based on the Z8001, which was reported to be a port
of MWC Coherent rather than based on the AT&T code.

The docs claim that there was an attempt to make it ABI compliant, but
the ABI wasn't "finalized" or something, so, future compatibility was

*shrug* Atari UNIX and Amiga UNIX seem close enough that some stuff
compiled on Atari works on the Amiga.
Out of curiosity, how much m68k SysV software was out there?

The install bits that have survived and escaped onto the Internet have
X11R4 with XView/OpenLook, no Motif/CDE. There was a port of X11R5 to
it that supported some of the newer graphics cards, but still no Motif.

Would be cool if someone found a tape and got it in the right hands.

Rumors were that *the* box that had the source on it crashed. Sounded
like a ridiculous reason to me, but that's what I'd heard.
