Re: PDP-11 Xenix (LONG) - TUHS

OK, Frank is likely correct.  But I still don't think you'll find it
anywhere
on the 'net!  It would be nice if it were in the PUP archives, though. 
Getting
it there might be hard because MS might still have some rights to it.

I did some digging, and here are some relevant dates:

 8/25/80   Microsoft announced DEC PDP-11 XENIX (along with versions for
several
           other machines--Intel 8086, Zilog Z8000, and Motorola
M68000).
           [This would have to be Version 7 based.]

10/01/80   Microsoft notes PDP-11 XENIX is "scheduled for release".
[It's not
           clear if this means it was actually released on that date.]

12/08/81   Microsoft and SCO signed a letter of intent for SCO to be a
second-
           source of XENIX.  [No mention of PDP-11; just that XENIX was
being
           upgraded to System III at that time.]

 1/22/85   Microsoft and AT&T announce plans for compatible future
releases
           of XENIX and UNIX [based on System V].

 1/31/86   Microsoft and SCO announce new agreements for SCO to be prime
distrubutor
           of XENIX System V to VAR and VAD channels.

 2/15/89   Microsoft makes 20% minority investment in SCO.  [I seem to
recall that
           SCO got (all?) XENIX rights at this time.]

So it looks like there was a window of about a year when a Version 7
based XENIX
was probably available.  Certainly starting in 1983 Microsoft announced
all sorts
of versions of XENIX for other hardware, including IBM System 9000 (yes,
there
really was a HAL 9000 (Motorola MC68000-based)--I had a couple), IBM
PC/AT, AT&T
UNIX PC and PC 6300, and Compaq machines.

 Since I'm the one that started this --- albeit indirectly --- let me try to
 explain.

 Way back when --- about 1981 or 82 --- I worked for a small (now defunct)
 software company.  We owned 2 PDP-11/23s.  Initially,  we ran a distribution
 of the Sixth Edition on them.  That came from a company in New York ---
 that's where I am geographically,  BTW --- called Yourdon.  The system was
 called UV6.

 After a while,  we decided to upgrade to V7.  At the time,  we had begun a
 relationship with another (now defunct) firm called Lifeboat Associates
 (also in New York,  later in Tarrytown, NY).  They distributed microcomputer
 software,  principally CP/M-based.  They were a Microsoft distributor.
 Microsoft had just started Unix development at the time.  Lifeboat sold us a
 V7 system:  Microsoft PDP-11 Xenix.  I know it was Microsoft because the
 tape lables said so, and I remember that the line printer printed release
 notes contained a banner page that indicated that they came from Microsoft's
 DEC 20(!) (cheerfully named "Microsoft Heating Plant").

 PD.-11 Xenix was essentially V7,  but it had a few added features.

  BTW,  if John or Bob reads this list,  l'd like
to say "Thank you" to both
 of them.  Also thanks to Warren for his work preserving the old Unix
 software.  It's a great deal of fun to see old "friends" again,  and I
think
 it will be just as much fun to see software and "hardware" combinations that
 I didn't have access to in the "good old days."  Thanks also to SCO for
 binary licenses for these "historic" systems;  I hope that they will be able
 to license source code in the near future.

 Sorry for the long ramble and thanks for reading!
