This is a program! It may be hard to recognize, but this is a plugboard from an IBM tabulating machine. You actually connect the processor structure to do different stuff, no microinstructions! - I've yet to understand completely how this works, but nevertheless, this is almost a work of art! It is not made by IBM, but a company called MAC PANEL in Belgium. There was a label on it stating that it is from 1970, so even at that time, it would've been obsolete, these were popular in the late 40's to the 60's. Presumably for the IBM 421 tabulating machine. The little grey plastic boxes are IBM branded hubs, interconnecting up to 3 of the plugs, which by the way, are 4mm banana plugs, though longer and "pointy". The program seems intact, no wires looks to have been tampered with (there's no dust on the edge of holes where plugs has been seated), so perhaps it's still executable!
Definitely a keeper.
