The university where I went in the mid 70s had a gaggle of Model 33 Teletypes in the engineering lounge (built like tanks, and sounding like them too) wired into a PDP-8 which ran a version of BASIC. You didn’t even have to authenticate, you just walked up and began a session. You had to type your whole program in and then run it as you sat, no storage, no media readers. Eventually they took the Model 33s away when someone spilled coffee into one of them.
Mine ran FORTRAN and it was really frustrating to me because I could not type worth a damn. I'd spend an hour typing a program in and then compile it only to get an error message that was always cryptic as hell. Then I'd have to sit there for another hour reading those fan fold pages to figure out where I made a typo.
I knew how the program, but I just couldn't convince the damn computer to run it. ;~))
