This web page has some details about XENIX prior to 1985:

In particular this chart is intriguing:

I’d love to have XENIX from the 1980-1985 era in the TUHS archive, as it documents the tail end of the Unix on 16 bits era. It would have been great if MS had released that as part of the Unix-at-50 events.

One of my first contracts with IBM was to add (get this) a SECOND network interface to secure-XENIX, an MLS version of the software.
I believe it was being used as a “downgrade” audit station to allow data to be moved form one secure network to another.    I believe the
original work was done by Jakob Recktor (probably butchering the spelling of his name).

That contract led to a few follow ons with IBM to port AIX to i860 based machines.    I still have my old IBM badge kicking around somewhere.

Perhaps even more significantly in this case, but possibly not
publicly known at the time, IBM's Project Chess, which resulted in the
IBM PC, apparently began in July 1980. (The promise was to develop an
initial prototype in 30 days, and a working personal computer in a
year; the initial demo was in August, the first internal demo in
January 1981, and product release was in August 1981.)

So by "mid 1980", what would eventually lead up to the IBM PC was at
most _just barely_ getting started.
