At least in the 80's, there was a BSD 4.3 port for the IBM PC/RT's that was called "AOS", for "Academic Operating System". For proof that my memory isn't playing tricks on me, here's independent confirmation :-) https://archiveos.org/aos/ At the time, it was pretty popular at MIT's Project Athena, mostly because the RT's were contemporaneous with the MicroVax's, but had three times faster integer operations, which made running TeX and LaTeX a far more pleasant experience for those of us who were typesetting papers and problem sets. :-) When AOS was sunset and Athena was frog-marched to use AIX, RT's suddenly became far less popular. :-/ - Ted
