That's how I remember Otis Wilson explaining it to us as
commercial licensees at a licensing meeting in the early 1980s.
We had finally completed the PWB 3.0 license to replace the V7
commercial license (AT&T would rename this System III - but we knew it as
PWB 3.) during the negociations   Summit had already moved on to the next
version - PWB 4.0.  IMO: Otis was not ready to start that process again.

Exactly, and Charlie Brown wanted to compete with IBM in particular—which
was an issue—by the time of Judge Green, the microprocessor-based
workstations had started to make huge inroads against the mini-computers.
AT&T management (Brown *et al*), still equated the "computer business" with
mainframes running Wall Street.

Right—that would have had to have been someone(s) in AT&T UNIX marketing in
North Carolina—the folks that gave us the "*Consider it Standard*" campaign.

I agree.  I take a WAG, though.   I >>suspect<< it was linked to the
attempt to sell the 3B20S against the DEC Vax family and the then IBM model
140 (which was the "minicomputer" size IBM mainframe system).   By that
time, System V was the OS Summit had supplied for it. If there were going
to be in the commercial hardware business, the OS SW had to match what the
HW used.
