Actually, what is the "man.tap" available here?

https://www.tuhs.org/Archive/Distributions/Research/Utah_v4/

I'm not somewhere I can dig around more than with od, certainly looks
like there are manpage sources in there.

>From the looks of it, nroff was missing from other, earlier versions
as well.  For instance, the s1/s2 bits tapes don't appear to have nroff
present despite it being in the V2 manual.  Is it known whether nroff
was primarily developed on the "trunk" MH PDP-11 or if it might have
lived elsewhere, leading to it not getting swept along for the tapes cut
for external users?
