[TUHS] Brian Kernighan and very early *roff history

[Angelo Papenhoff]

Since the topic is on the history of troff, I'd like to mention again
that to my knowledge no troff version before the C rewrite in v7
is publicly available anywhere. v6 only has nroff, v5 only has roff
even though nroff/troff appeared in v4.
The v6 distribution has deleted directory entries for troff source
but not the files themselves.
I hope it is not lost. Maybe someone here has an idea where it could be
found?
