Hello Pete,

Remember that, in the 1980s, Microsoft was working on its own version
of UNIX. They licensed it from AT&T and renamed it Xenix. /Deja vu/?
Indeed ! But wasn't there some agreement that prevented M$ marketing
it !
"Microsoft did not sell Xenix directly to end users; instead, they
licensed it to software OEMs such as Intel, Tandy, Altos and SCO, who
then ported <http://en.wikipedia.org/wiki/Porting> it to their own
proprietary computer architectures
<http://en.wikipedia.org/wiki/Computer_architecture>. Microsoft Xenix
originally ran on the PDP-11 <http://en.wikipedia.org/wiki/PDP-11>; the
first port <http://en.wikipedia.org/wiki/Porting> was for the Zilog
<http://en.wikipedia.org/wiki/Zilog> Z8001
<http://en.wikipedia.org/wiki/Z8001> 16-bit processor
<http://en.wikipedia.org/wiki/Central_processing_unit>. Altos
<http://en.wikipedia.org/wiki/Acer_%28company%29> shipped a version for
their computers early in 1982 <http://en.wikipedia.org/wiki/1982>, Tandy
Corporation shipped *TRS-XENIX* for their 68000
<http://en.wikipedia.org/wiki/68000>-based systems in January 1983
<http://en.wikipedia.org/wiki/1983>, and SCO released their port to the
Intel 8086 <http://en.wikipedia.org/wiki/Intel_8086> processor in
September 1983 <http://en.wikipedia.org/wiki/1983>. A port to the
68000-based Apple Lisa <http://en.wikipedia.org/wiki/Apple_Lisa> also
existed. At the time, Xenix was based on AT&T's UNIX System III
<http://en.wikipedia.org/wiki/UNIX_System_III>.
"Version 2.0 of Xenix was released in 1985
<http://en.wikipedia.org/wiki/1985> and was based on UNIX System V
<http://en.wikipedia.org/wiki/UNIX_System_V>. An update numbered 2.1.1
added support for the Intel 80286
<http://en.wikipedia.org/wiki/Intel_80286> processor. Subsequent
releases improved System V compatibility.
"When Microsoft entered into an agreement with IBM
<http://en.wikipedia.org/wiki/International_Business_Machines> to
develop OS/2 <http://en.wikipedia.org/wiki/OS/2>, it lost interest in
promoting Xenix. In 1987 <http://en.wikipedia.org/wiki/1987> Microsoft
transferred ownership of Xenix to SCO in an agreement that left
Microsoft owning 25% of SCO."
