The ditroff conversion before the releases of Documenter's Workbench?

For reviewing C/A/T troff output it might be easiest to use Adobe 
transcript, which included ptroff to convert from otroff to postscript.

Transcript is on disc 4 of Kirk McKusick's CSRG set under 
local/transcript in source and binary form for the Vax.  There's a 
version of public domain ditroff from 1981 in local/ditroff on that disc 
as well.  Running 4.3 Reno from disc 2 or TUHS on a Vax in simh and 
pulling the software off disc 4 would cover your bases pretty well.

Alternatively, you can also find an earlier version of transcript in 
binary form on Apple AU/X and a later version from 1987 on 
Nextstep/Openstep if you already run either of those in emulation.

The open source psroff from Chris Lewis is another option, but takes a 
lot more work to compile.


Best,

Dan Plassche
