no.

yes to both

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.
