Just to bring it full circle, after a bit of discussion it looks like what Henry is working with is the initial System V release for PDP-11/70, not some fabled PDP-11 SVR2, so the documentation I linked as well as some material on squoze.net concerning System V in SimH all apply directly. Subject adjusted accordingly.

I'm not aware of any discovery of TROFF sources for any of this stuff past System III, I do have it on my long-term list to eventually synthesize copies of said documents from available scans so they can be more easily diff'd, but my current focus is much, much earlier.
