  Thanks for reminding me, Branden. :) I've
yet to get V7 Unix working with
 the latest release of SimH, so that's kind of stalled my ability to develop
 something in K&R-friendly  C.  
 I went ahead and write a little C/A/T-to-later-troff-output converter in
 v7-friendly and C89-conforming C:

 https://git.sr.ht/~humm/catdit 
This is an exciting prospect but I can't actually see anything there.

I get an error.

  I’m not confident in having got the details of spacing
right (Is that
 55-unit offset when switching font sizes correct?) 
I've never heard of this C/A/T feature/wart before.  Huh.

...
  and the character codes emitted are still those of the
C/A/T,
 resulting in the wrong glyphs being used. 
The codes should probably be remapped by default, with a command-line
option to restore the original ones.  I would of course recommend
writing out 'C' commands with groff special character names.

...
  I created the attached document like this:

 	v7$ troff -t /usr/man/man0/title >title.cat
 	host$ catdit <title.cat | dpost -F. -Tcat >title.ps

 (Where do the two blank pages at the end come from?) 
Good question; we may need to rouse a C/A/T expert.

...
  PS: Branden, for rougher results, if you happen to
have a Tektronix
 4014 at hand (like the one emulated by XTerm), you can use that to
 look at v7 troff’s output.  Tell your SIMH to pass control bytes
 through and run troff -t | tc. 
I'd love to, just please make your repo available to the public.  :)

Regards,
Branden
