The 586 was not the first Xenix system from Altos -- their first as I
recall was an overpriced and unreliable 68000 system. The TRS-80
Model 16 blew it away, so Altos switched over to the 8x86 and after a
while converted to SCO -- as Tandy did later, much to my annoyance.
Microsoft was never able to create a viable consumer product out of
Xenix, although they picked up a lot of good ideas during the effort
of starting the project, which is why MS-DOS went beyond its
CP/M-clone beginnings to add features such as the tree directory,
(fake) I/O redirection, (fake) pipes, (fake) device independence,
etc.. starting with version 2.0. They sublet the project to Altos,
Tandy and SCO in that order, which companies actually produced
products. SCO having no other business _except_ software naturally
went for the 8x86 market, and eventually dominated that end of the
Unix business for quite a few years, and now they own the rights to
all of the original AT&T source code via the buyout from Novell. Of
course, they're losing ground to Linux every day. And they _don't_
own the Unix trademark -- that's owned by The Open Group.

(Tandy Xenix is where I fell into the black hole of Unix, and there's
a Tandy 6000HD with a slightly ailing hard disk controller less than
six feet from me which I _will_ resurrect).
Oh, Altos Xenix appeared in early '82, Tandy Xenix in Jan '83, and SCO
started shipping software in Sept '83. The latter two from personal
memory, as I was actually paying attention at the time. The initial
SCO offering for the XT left much to be desired, the AT version was a
_lot_ better, but they conquered the market with Xenix/386.
