[TUHS] Was curses ported to Seventh Edition Unix?

Hi folks,

I'm finding it difficult to find any direct sources on the question in
the subject line.

Does anyone here have any source material they can point me to
documenting the existence of a port of BSD curses to Unix Version 7?

I know that curses made it into 2.9BSD for the PDP-11, but that's not
quite the same thing.

There are comments in System V Release 2's curses.h file[1][2] (very
different from 4BSD's[3]) that suggest some effort to accommodate
Version 7's terminal driver.  So I would _presume_ that curses got
ported to Version 7.  But that's System V, right when it started
diverging from BSD curses, and moreover, presumption is not evidence.

Even personal accounts/anecdotes would be helpful.  Maybe some of you
_wrote_ curses applications for Version 7 machines.

Regards,
Branden

[1] System III apparently did not have curses at all.  Both it and 4BSD
    were released in 1980.  System V Release 1 doesn't seem to, either.
