For once a vintage piece of electronic equipment that actually worked right off the bat and needed no heroic repair! That's because it is no ordinary card puncher. It used to belong to Frank King, member of the IBM 1401 restoration team at the Computer History Museum, and great guru of card punchers and readers. I just cleaned it up a bit and my daughters are already having a lot of fun with it. Here they are punching a card, then feeding another one and making a duplicate.
