1972 Unix V2 "Beta" Resurrected

I love this!

first time I see people use 'ed' for work!!!

I wonder who else has to deal with ed also... recently I had to connect to an ancient system where vi was not available, I had to write my own editor, so whoever needs an editor for an ancient system, ping me (it is not too fancy).

amazing work by the creators of this software and by the researchers, you have my full respect guys. those are the real engineers!

I remember using an ed-like editor on a Honeywell timeshare system in the 1960s, over a Teltype ASR-33. I don't remember much except you invoked it using "make <filename>" to create a new file. And if you typed "make love" the editor would print "not war" before entering the editor.

The “MAKE LOVE”/“NOT WAR” easter egg was in TECO for DEC PDP-6/10 machines. But DEC TECO was also ported to Multics, so maybe that was the Honeywell machine you used it on.

But, for a whole bunch of reasons, I’m left with the suspicion you may be misremembering something from the early 1970s as happening in the 1960s. While it isn’t totally impossible you had this experience in 1968 or 1969, a 1970s date would be much more historically probable
