Ken ShirriffThe Computer History Museum has a presentation tonight on the history of computer dating: "Algorithms of Love". I made a special punch card for the event. It wasn't easy to make this card so I'll explain how I did it...
Michael Silves@kenshirriff The card is upside down. The corner cut is always on top.
@Datamorph I got most of them right side up, just not the one in the photo 🙂
