TMG was in v2-v6, sometimes in man1 and sometimes in man6.
I have an apparently complete source listing. The year is
uncertain. (Back then date headings from pr didn't mention the year!)
The accompanying manual, though, is dated 1972. There is also, besides
the TMGL definition of TMGL, a TMGL definition of pig Latin as a
simple test case.
None of this is useful, though, without a PDP-11 binary for tmg--
the usual chicken-and-egg problem with a full-blown compiler written
in its own language.

Speaking of
TMG, is there an implementation for FreeBSD/Mac/Linux? Or do
I have to find a CDC/PDP-7 emulator first? :-)

TMG is mentioned in the v3 manual:
/sys/tmg/tmgl.o -- the compiler-compiler
There's no files for it for v5 but it is in v6 and it seems to
disappear after that.
On TUHS V6/usr/source/tmg/tmgl.t would seem to be a source file.
I did manage to get something running for pdp-7 on simh and got to the
GA prompt.
Didn't get it to do much beyond printing "CAB DECSYS7 COPY 15 JUNE
1966"

Hmmm... I haven't used YACC for many years (not since my CompSci days,
when I was considering a Pascal->C translator for my thesis; I had
threatened to write it in SNOBOL) so if a suitable rainy day comes along
(and I can get the manpage etc) I might give it a stab.
