A couple of days ago I had the pleasure of meeting Walter Taucher. Among other things in his Seattle office, he has a card-punch machine from the thirties.
Yes, kids, the connection between your keyboard and your computer used to be, not a USB cable, but a stack of cards that you’d carry across the campus to the computer building. This was the thing that punched the cards. Part of the intrigue for me was that this came from a company we know well, but which now has a rather different logo.
