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. ;~))
Punch cards, which were available in the main computer facility housed in the mathematics building, seemed such a godsend. You could pull the bad card out of the stack and throw it away, putting a good card in its place.
