Good lord, a hand operated card punch. I know the exist but I’ve never used one. Good for fixing *a* card, but you wouldn’t want to input a whole program making cards that way.

In 1981 I was the only person in my freshman programming class that knew how to run a keypunch machine. The upper class people got to use DEC 100 terminals. By junior year I had a computer in my dorm room and a modem to the computing center.
