EMACS ran on ITS, TOPS-20, and TENEX, but not TOPS-10. TOPS-10 had
Emacs-likes FINE and AMIS.
Thanks -- you're right. FINE was what we had on the PDP-10s, not pure EMACS, which we did not get until we started running TOPS-20. As I said, i used it for such a short time and never really mastered it but the time I switched to UNIX. Which set me on a path to ex/vi and by the time Gosling EMACS was available, I had never went back as ex/vi was getting the job done and ran on both PDP-11s and Vaxen. It was just not worth re-learning it as vi was by the, everywhere from MS-DOS to the Cray 1 and EMACS wasn't.
