Rich - thanks, that's the paper I referred to. Note date -- 6-Jan-80 - the
work being done in the summer of '79. A number of us had been using
ditroff as it had existed for a couple of years by that time, and as the
abstract says - they got the Mergenthaler in the Summer of '79. What I did
not remember was when the Mergenthaler work started. I did remember that
it was after the APS-5 had been available for a while.
Just for completeness, Judge Green mandated the breakup of the Bell System
on January 8, 1982 -- Tool Chest *et al*. is set up later -- all part of
the ability for AT&T to be in the commercial computer business.

has some papers
with Brian as co-author that talk about the history or the 202 and the
background work (troff->ditroff) involved.
I am sure these have been posted here before.
