Here's what I've got so far, trying to pin down the origins of
Xenix. It fails utterly to tell a consistent story, so any tips
will be appreciated:

[This article seems the most credible to me.]

1984: IBM AT causes MS to resume interest in Xenix-286
http://groups.google.com/groups?selm=GMrt5J.y23%40nemesis.lonestar.org
So can anyone suggest a series of release-dates for the various
early Xenixes (8086, 68k, Z8000, 286, PDP11, etc) that makes
sense of all this?
A Series/1 port was actually done around this time by a now dead company
called COSI (unrelated to the sandwich shops). I paper on this appeared
in Communications of the ACM some time in the early 80s. Stolarchuk was
one of the authors.

I did some (more) searching thru the Google archives under his name,
and found a pretty convincing claim that the first MS Xenix release
was late 1982, presumably for 8086, followed in 1983 by the Tandy
Xenix for 68000.
He thinks c1981 MS only had two programmers assigned to Xenix ports.
(If one of them was Bob Greenberg, he left MS in '81, which would
have set things back even more.)
A PPOE had an Altos 8086 machine running Xenix is late winter or early spring
of 1982. It may have been a prototype, though.
Sorry for one little correction...
IIRC that was supposed to be Western Electric (WECO -- the manufacturing
arm of AT&T -- later a part of Lucent) not Western Digital the
manufacturer of the LSI-11 chipset and a large number of IDE drives
and chipsets.

Begging Western Digital for a Unix license had absolutely ZERO chance
of accomplishing anything useful. I very much doubt that Microsoft
ever did that.
