That is a good point: early Xenix is still missing. It would make an excellent public relations move for Microsoft if they would make early Xenix available to celebrate 50 years of Unix.

Call me a cynical old bastard (which I am), but I can't see M$ raising a flag for Unix...  Wasn't it Billy Gates who reportedly said that any PC running Linux is one not running Windoze, and did his best to discredit it?

I still have horrible memories of porting Unify (an early RDBMS) to Xenix, and getting tangled up in the poxy small/large memory models on the equally-poxy 286 (no, not the 386).


I can understand no love for Xenix on this list, but actually M$ is part of the UNIX history and was actually quite successful with Xenix[1].  In the late 80s there were more computers running M$ Xenix than all other versions of UNIX combined.

Some good history here:
