I don't know where these go either but I'm interested in this stuff too.

That is basically what it means.  Microsoft apparently ported Version 7 and
rather than scrap that work and start over for System III, they made it look
like System III to the user.  Many companies have done this for thier upgrades
to System V from System III.  A good example is the Unisoft port that I have
seen on the Cromemco, NCR and other machines.

I will write later about what I know about Xenix 3 when I get it all together,
but let me comment about Xenix System V.  It is, apparently, an all new
port so it should not be a System V built on the old Xenix.  I am very 
interested in hearing from people who are beta testing the software.  I port
software for a living and getting burned when people claim a system is
one thing and I find out it is another underneath.
