[There seems to be a thread of confusion here w.r.t. troff vs. nroff]

To clarify:
    1) nroff *does* work with tbl (but you have to pipe the output
       of nroff thru col to avoid scrambulation due to reverse
       line feeds).  I imagine you also have neqn which attempts to
       take nroff's limitations into account and give you a "reasonable"
       representation of eqn.
    2) Psroff (1.0, 2.0, 3.0) works with C/A/T *troff*, not nroff.  C/A/T
       Troff is also part of the Xenix Text Processing Package.  And Xenix's
       troff and psroff work together quite well.  Quite a number of
       people are using Xenix's C/A/T troff with psroff without any
       trouble on postscript and HP Laserjet printers.  (Psroff 3.0 also works
       with ditroff aka DWB, and even groff if you need good HP Laserjet
       output)

As far as I'm aware, SCO's troff is no worse than any other C/A/T troff.
There was a rumor (back in psroff 1.0 days) that there was something
odd about Xenix Troff's offset and pagelength, but I was unable to
confirm precisely what the problem was.

I think you already have all the bits.  *Except* pic and grap.  If you
need to run pic (line drawing) or grap, I suggest you get groff as
Ronald has suggested.  Psroff does a very good job with C/A/T troff,
and as long as you don't have to do much in the way of line drawing, need
kerning, or go totally bonkers with fonts (C/A/T troff has some
limitations on number of fonts available per line), psroff will
do what you want, faster than groff.

Does groff support mm now?
