Subject: canonical answer about Sixth and Seventh Edition
So far as I can determine, AT&T doesn't think it has the
right to issue new licenses for any Unix editions, and won't
do so. Several years ago, the Unix IP was transferred to
Unix Systems Laboratories, at first as a mostly-owned subsidiary;
USL was then sold to Novell, and recently Novell agreed to
sell its Unix business to SCO (and HP is partially involved).
As of the end of October 1995 this last sale had not been
In other words, AT&T is out of the Unix business, and has been
for some time; any licenses will have to come from the current
owner. But the "current owner" is itself in flux, and I doubt that
even before the latest sale, Novell was quite geared up to issue
Seventh Edition licenses; I have no useful suggestions about
how to obtain one officially (it might be interesting to try).
Official sources in AT&T have said that they have no objection
to reissuance of Lions's commentaries and source publication
of the Sixth Edition.
So it doesn't look like good news at the moment; I guess we could approach
SCO and HP, and ask about trying to get licenses from them. I'll see what I
A few other people mentioned that they would like to get stuff from the
archive of early Unixes that I'm maintaining, and how to prove that they have
a license. I have no idea how to do this, any suggestions?
P.S There isn't a Sixth Edition in the archive as yet, can anyone send me a
distribution or bootable disk image?
