Termcap and termlib from 2BSD should work fine on standard V6/V7 -
that's what they were originally written for. You don't need curses for
vi or emacs, they have their own comparable code internally. In fact,
the original 2BSD curses from Ken Arnold was basically the vi code
pulled out into a separate library.
Warren Montgomery's emacs was internal to Bell Labs and intended for
Bell Labs versions of PDP-11 UNIX, not 2BSD, although I recall it was
often ported to the Vax. I can't recall which version of UNIX they ran
in the various Computer Centers in the early 1980s when this happened,
but I doubt it was V7; probably PWB or UNIX/TS. It would have had the
Ritchie C compiler. I can't recall if it used termcap or had the
terminals hardcoded - apparently both, according to this:

Two more thoughts...
1.) Zimmerman EMACS (a.k.a. CCA EMACS) ran on the PDP-11 originally
when Steve wrote it at MIT. It's the closest to the original
ITS/PDP-10 emacs of all the originals that I knew. I'm pretty sure
he converted it to Pavel's freely available terminfo implementation at
some point (when he was at Masscomp), but I think the original
Zimmerman code has screwed down terminal support to a couple of
terminals that were used at MIT. I've lost track of Steve, but I'll
see if I can find you an email by reaching out on an Alumni list.
2.) I believe the first (joy created) termcap was in 2BSD but I don't
think Arnold and Horton had started to pull the curses library out of
vi yet. I think termcap itself had been but Mary Ann would be more
authoritative than I. Check out the 2BSD, 3BSD, and 4BSD releases and
look for the earliest versions. The C compiler is pretty much the
same in all cases (the only issue I can think is that by 3BSD folks at
UCB had removed dmr's 7 character variable limit), but I think curses
should compile without too much issue on a virgin dmr V7 compiler.
