I have a very similar manual; I got it a long time ago, and no longer recall
how I came by it. Minor difference: mine is for PD-1C301-01, and at the
bottom of the page, it says "ISSUE 1 1/30/76", followed by a prominent trade
secret notice.
TUHS has a copy of this version, here:
https://www.tuhs.org/Archive/Distributions/USDL/unix_program_description_ja…
The README file in that directory:
https://www.tuhs.org/Archive/Distributions/USDL/README
speculates that "this is PWB/1.0" but admits "this has not yet been
confirmed". It's not PWB1, it's stock V6. If you look at the writeup of
sys1$exec(), on pg. 39 of the PDF, you'll see it describing how arguments are
copied into a disk buffer; that right there is the tip-off. In PWB1 (whose
source we do have):
https://minnie.tuhs.org/cgi-bin/utree.pl?file=PWB1/sys/sys/os/sys1.c
you'll see that PWB1 accumulates the arguments in a chunk of swap space.
V6 _does_ use a disk buffer for this:
https://minnie.tuhs.org/cgi-bin/utree.pl?file=V6/usr/sys/ken/sys1.c
So this is for V6.

2. My EXEC (II) manual page has BUGS:
"Only 512 characters of arguments are allowed"
So my manual, like yours is not for PWB.
BUT, my manual describes system call 62, "lock", and the v6 sysent.c
has "nosys" there, so it's at least in theory, an offshoot.
I haven't spotted anything in the
unix_program_description_jan_1976.pdf document regarding lock
Searching for the names in the preface of my manual I found:

later show up in the compiler on the phototypesetter version 7 tape.

usr/source/c_compiler/ on the unsw3 tape may be close to that compiler,
it isn't the same as the pwb compiler.

"a new tape is in the process of preparation, and should be available as
soon as it clears the lawyers, for the usual free license and handling
fee. It contains the new nroff, the new C, the new I/O library (faster
& smaller than anything to date), and a bunch of other such things. It
will be available from Bell, not the Center. Ken is going to send a
formal notice to the News."

Jonathan Gray asked:
Is there an access() system call?
https://minnie.tuhs.org/pipermail/tuhs/2021-November/024657.html
no.
or alarm() and pause() system calls added in the v6
"50 changes"
yes to both
or changes to C such as libS/stdio, unsigned and
typedef which would
later show up in the compiler on the phototypesetter version 7 tape.
https://www.darwinsys.com/history/hist.html
usr/source/c_compiler/ on the unsw3 tape may be close to that compiler,
it isn't the same as the pwb compiler.
The getc and putc man page synopsis look identical to the ones at
https://man.cat-v.org/unix-6th/3/
Section VI differs from https://man.cat-v.org/unix-6th/6/
Mine has (in addition to those in v6)
agen -- generates associative memory drivers
hyphen -- find hyphenated words
lex -- generate programs for simple lexical analysis
ptx -- permuted index
tmac -- -ms macros which is ms(vii) in v6
And from v6 is missing: azel col graph m6 plot quiz sky speak spline tbl tmg
Compared to the v7 lex, the one command line argument is "-code",
equivalent to a first input line of "%-code" which changes the output
prefix from "yy" to "code".
Compared to v6, Section I is missing: eqn, lpr, man, neqn, newgrp,
opr, rc, rev, roff, spell, tee, troff.
But has:
lc (LIL compiler)
mtm (magnetic tape manipulation),
onintr (specify interrupt handling for a command file)
read/open/onend (sequential file read)
req (rewind tape)
sum (sum file)
The one man page I compared is yacc(I) which is missing the '-r'
(ratfor) option present in v6
The manual is typeset, and the inside of the cover page days "This
manual was set by a Grahpic Systems phototypesetter driven by the
troff formatting program under the UNIX system. The text of the
manual was prepared using the ed text editor"
No sign of new archive format.
I have only the manual pages, so I can't speak to the state of C.
