For me, it was wait until the next evening until I found out how many typos I had made typing up the damn punch cards.
Yeah, I be that old.
Yeah, my first computer class was on punch cards. Second was on time-share terminals. Then when I was in grad school, I had the PC. So I sort of saw it all in my college years.
As freshman undergrads, we used to get two runs a day, and had to leave our decks in the top drawer of a file cabinet in the Physics building. There were usually rubber bands in there, for our convenience, but on one occasion, there were none, much to my consternation. My reaction was to bellow a heartfelt, WELL F*** ME IN THE A**H*** ! ... and then I looked up and there was a girl sitting in the room “studying” as was the particular habit of girls in those days. She was starting to turn around, but I assure you she never saw me!
