Xenix Exploration
From Toxi's Wiki
What's Xenix?
Xenix is a variant of System V Unix AFAIK created by Microsoft and then sold off to SCO. However, Xenix featured multiple technical improvements over System V Unix.
It was ported to many different platforms, like the Altos 8600, IBM PC, etc. Although the one I'll mostly be here for is the IBM PC compatible versions.
What Used Xenix?
Apparently, to the mid-to-late 1980s, Xenix was the most common variant of UNIX. Also, in around DOS 2.0 time, they introduced subdirectories -- a feature taken from Xenix. Apparently they had intentions to turn DOS into a sort of 'single-user' Xenix. Oh, also, they used Xenix, to compile the first versions of Windows -- in fact, you could cross-compile from Xenix to DOS.
