I would hardly call troff "open source", at least not "back in that era".  
When I first started using roff and nroff, you had to sign all sorts of 
non-disclosure paperwork to get a copy of Unix.  It wasn't until much later 
that things like the BSD and GNU projects started coming out with open 
source versions.

Of course, the whole roff family is based on the old runoff program (which 
in turn was probably based on something else).

Anybody remember Scribe?
