I don't really know how deeply you've looked into this, but it may be
of
interest to you that Wollongong v6 on Interdata 32 has C sources for
troff in /usr/source/troff:
http://www.bitsavers.org/bits/Interdata/32bit/unix/univWollongong_v6/interd…
I know you're looking for assembler, but I also saw the comment "C
rewrite in .. v7" in the message. It looks like a C version was
available for v6. According to Miller's note:
interdata_v6.tar.gz
a 'tar' format archive (with dates preserved) of all files as
they would appear after installing the distribution, with source
and documentation in /usr/source and /usr/doc respectively; note
however that special files in /dev appear as ordinary files
The troff dir has date Jun 6, 1978. According to the readme, it was
untested (maybe even unported?).

to my knowledge no troff version before the C
rewrite in v7
Apologies if I missed something, but between this list and COFF there's so
much low S/N traffic I skip a lot of it. Having said that, was there ever a
troff in assembler? I'd always had the impression that the first one was in C.
So that one is a "troff version before the C
rewrite in .. v7", but it is in
C. Is that of any interest?
Without having looked into it more than you have it
looks like it is
just an earlier version of the C code, but what I'm after is the
original assembly.
