I picked that one because it said it had derived from a 1986 original, so I guessed that if I went back to the initial GH commit I'd get something that was K&R C and not a million miles away from v7, and I was right. I...can't believe I never thought of just tossing some #defines up top. I feel *really dumb* now, especially given the gyrations I went through with gnusto to rewrite the symbol table to get Frotz to work on TOPS-20. Yes, letting the preprocessor rather than sed do my work would have been cleaner. Anyway, https://github.com/athornton/microemacs-v7 It does, however, seem to be limited to files a couple dozen K in size, because even MicroEMACS is still kinda large, and a PDP-11's memory is kinda small.

It's Microemacs 3.6 As far as I know, the first Emacs on a PDP-11 was written by MIT alumnus Warren Montgomery at Bell labs. https://github.com/larsbrinkhoff/emacs-history/blob/sources/docs/Montgomery%20Emacs%20History.txt https://github.com/larsbrinkhoff/emacs-history/tree/sources/ana-3.lcs.mit.edu/%7Ejnc/tech/unix/emacs https://github.com/larsbrinkhoff/emacs-history/tree/sources/www.tuhs.org/Archive/Distributions/Research/Norman_v9/batterpudding.tar.gz/cmd/emacs > Arrow keys, naturally, don't work, but C-b, C-f, C-p, C-n do. As is good and proper.
