Although I edited the v7 through v10 manuals, I have no recollection of
why "system" crept into the title between v7 and v8. Resistance to
trademark edicts did grow. In v10, the cover and the man pages proclaimed
"Unix". However, the fossilized spelling, "UNIX", still appeared in the
introduction to Volume 1 and scattered throughout Volume 2.

So in most technical circles and indeed in the research communities surrounding
UNIX, the name of the system was just that, UNIX, prefixed often with some
descriptor of which stream, be it Research, USG, BSD/Berkeley, but in any case
the name UNIX itself was descriptive of the operating system for many of its
acolytes and disciples.
However, in AT&T literature and media, addition of "System" to the end of the
formal name seemed to become de facto if not de jure. This can be seen for
instance in manual edits in the early 80s with references to just "UNIX" being
replaced with variations on "The UNIX System", sometimes haphazardly as if done
via a search and replace with little review. This too is evident in some
informative films published by AT&T, available on YouTube today as
"The UNIX Operating System" and "UNIX: Making Computers Easier to Use"[1][2].
Discrepancies in the titles of the videos notwithstanding, throughout it seems
there are several instances where audio of an interviewee saying
"The UNIX System" were edited over what I presume were instances of them simply
saying UNIX.
I'm curious if anyone has the scoop on whether this was an attempt to echo the
"One Bell System" and related terminology, marketing tag lines like
"The System is the Solution", and/or the naming of the revisions themselves as
"System <xyz>". On the other hand, could it have simply been for clarity, with
the uninitiated not being able to glean from the product name anything about it,
making the case for adding "System" in formal descriptions to give them a little
bit of a hint.
Bell Labs folks especially, was there ever some grand thou shalt call it
"The UNIX System" in all PR directive or was it just something that organically
happened over time as bureaucratic powers at be got their hands on a part of the
steering wheel?

"Patch" connotes individually distributed small fixes, not complete
working systems. I don't believe Brendan meant that v8 was only a patch on
v7, but that's the natural interpretation of the statement.
V8-v10 were snapshots, yes, possibly not perfectly in sync with the
printed editions. But this was typical of Research editions, and especially
of Volujme 2,
which was originally called something like "Documents for Use with Unix".

Hi Alex,

A. I don't think we know for sure which version of troff was used to
format the V10 manual. _Probably_ Kernighan's research version,
which was similar to a contemporaneous DWB troff...but what
"contemporaneous" means in the 1989-1990 period is a little fuzzy.
Also, Kernighan may not have a complete source history of his
version of troff, it is presumably still encumbered by AT&T
copyrights, and he's been using groff for at least his last two
books (his Unix memoir and the 2nd edition of the AWK book).
B. It is hard to recreate a Research Unix V10 installation. My
understanding is that Unix V8-V10 were not full distributions but
patches. And because troff was commercial/proprietary software at
that (the aforementioned DWB troff), I don't know if Kernighan's
"Research troff" escaped Bell Labs or how consistently it could be
expected to be present on a system. Presumably any of a variety of
DWB releases would have "worked fine". How much they would have
varied in extremely fiddly details of typesetting is an open
question. I can say with some confidence that the mm package saw
fairly significant development. Of troff itself (and the
preprocessors one bumps into in the Volume 2 white papers) I'm much
more in the dark.
C. Getting a scan out there tells us at least what one software
configuration deemed acceptable by producers of the book generated,
even if it's impossible to identify details of that software
configuration. That in turn helps us to judge the results of
_known_ software configurations--groff, and other troffs too.
D. troff is not TeX. Nothing like trip.tex has ever existed. A golden
platonic ideal of formatter behavior does not exist except in the
collective, sometimes contentious minds of its users.
> Doesn't groff(1) handle the Unix sources?
Assuming the full source of a document is available, and no part of its
toolchain requires software that is unavailable (like Van Wyk's "ideal"
preprocessor) then if groff cannot satisfactorily render a document
produced by the Bell Labs CSRC, then I'd consider that presumptively a
bug in groff. It's a rebuttable presumption--if one document in one
place relied upon a _bug_ in AT&T troff to produce correct rendering, I
think my inclination would be to annotate the problem somewhere in
groff's documentation and leave it unresolved.
For a case where groff formats a classic Unix document "better" (in
the sense of not unintentionally omitting a formatted equation) than
AT&T troff, see the following.

I've opined before that the various aspects of Unix "IP" ownership
appear to be so complicated and mired in the details of decades-old
contracts in firms that have changed ownership structures multiple
times, that legally valid answers to questions like this may not exist.
Not until a firm that thinks it holds the rights decides it's worth the
money to pay a bunch of archivists and copyright attorneys to go on a
snipe hunt.
And that decision won't be made unless said firm thinks the probability
is high that they can recover damages from infringers in excess of their
costs. Otherwise the decision simply sets fire to a pile of money.
...which isn't impossible. Billionaires do it every day.

It's the kind of thing I've thought about doing. :)
If you do, I very much want to know if groff appears to misbehave.
