Emacs in 1983 would have been Gosling Emacs, I guess.
Prior to that one, someone else at BBN (whose name I have forgotten, alas)
did an Emacs intended for PDP-11's running Unix. It wasn't programmable (the
way 'real' Emacs is), perhaps because there was not enough room for that on a
PDP-11.
I should have that on my MIT-CSR backup tapes, but if you're interested in a
copy, it will be a while before I can excavate it; the tapes had some
dropouts, which may have made the dump (a straight 'dd' of a 4.3 filesystem)
unreadable.
