Not listed on the "complete" list is XINU,
which is an educational
operating system developed at Purdue University by Dr. Comer (his
students, and others) and was taught on LSI-11s for a number of
years before newer more modern processors took their place.
"XINU" == "Xinu Is Not Unix"

Hmmm, in taking another look at the list, I'm guessing that the author chose
to group all UNIX varients except Ultrix and Venix under "UNIX". Kind of
odd when you consider how many RSX varients are listed.
