I got release 2.0 of AT&T's Documenter's WorkBench (which includes
eqn, grap, pic, tbl, troff, nroff, -mm, and other stuff) ported to
Sun-3s a few years ago.  If you have an AT&T DWB 2.0 source license,
contact me to arrange for a copy.  You might also consider contacting
SoftQuad in Toronto; they've enhanced DWB and provide it WITH support
for a variety of systems.

I have no idea why Sun doesn't wish to offer DWB themselves.
