No, not Win9x, and not MS-DOS - a not even OS/2.

Refresh your memory...

So, does anyone know more?

Its funny how Microsoft can't even spell the word "are'nt"...

ITS "AREN'T", BILL!!!

if i recall correctly, microsoft sold off xenix to someone else.

That's true. It was transferred to SCO ([url]http://www.sco.com/[/ur])
at some point, and in some shape or form, but that's not the
end of the story. For example, the Run-time Library Reference
for version 8 of the MS C compiler, printed in 1993, still says:

Microsoft, MS, MS-DOS, XENIX, and QuickC are registered
trademarks and Windows, etc... are trademarks of Microsoft
Corporation in the USA and other countries.

I also seem to recall that SCO had to pay royalties to Microsoft
for a long time, and that there was a legal dispute about it.

Changes in the MS-DOS Unix-compatibility suggests a
distinct shift in company policy at some point between MS-DOS
3.0 and 4.0. For example, the 4.x command line utilities
stopped paying attention to the "switch-char" setting (the
primary purpose of which was/is to allow the use of
Unix-style '/'-separated paths that would otherwise conflict
with the use of '/' as a command-line option character).

IT'S "IT'S" gamehead!

Sorry, I just couldn't resist..................

Sad, really. Xenix was the last of the 8-bit Unixes.

Quiet... I missed the apostrophe...

8 bit OS?

Heck, I'll take the "Commodore 64".

Best little 8 bit machine that ever came down the pike.
I still have mine, with my exclusive, custom Kernal.
