[net.wanted] What is UN*X ?

zulu@bmcg.UUCP (05/08/84)

I have recently been seeing the acronym "UN*X" being used on the USENET.

What does it mean? Is it like a regular expression, allowing one to 
transform it into UNAX, UNEX, UNOX, UNUX, or even UNGX?  If so, what
is UNGX?  Please mail me if you have any clue whatsoever.

Seriously perplexed,
