That is brilliant. If I got one, I'd fill it up though. lol

My dad had some similar ones he brought home from his job working on the IBM mainframe at MSU (or maybe Sparrow Hospital, before that?). When they scaled back their use of punch cards, they got rid of several of those sized cabinets. I think those cards were sized about 8 or 9 inches by 3.5" or so.

Definitely could have adapted them. But I'm not sure what happened to them? Probably got sold at the big garage sale, when they moved out of East Lansing to retire.
