Clem,
Once again, you have the timeline wrong on all this. The ditroff work
was started in the summer of 1979, well after V6, Typesetter C and
V7. Details are available at https://www.cs.princeton.edu/~bwk/202/202paper.pdf
and https://www.cs.princeton.edu/~bwk/202/summer.reconstructed.pdf.
Perhaps Doug can set the history straight on troff. Here is my understanding,
corrections (from Doug) welcome:
- Ossanna wrote the original nroff in assembly language
- He rewrote it in C when the C/A/T was acquired
At that time nroff/troff were built from mostly the same sources (as
can be seen in the archives).
Thanks,
Arnold
