Look what I found...

liudr:
There is a panel in my work place that someone kept. It's got hundreds of jumper wires on a matrix of holes. He said it was a program someone made. That stuff IS older than punch cards.

Not sure about the model numbers and other specifics, these were just slightly before my time but I do think I remember them being wheeled out the door. I did have an assignment for a few weeks once that involved operating a card sorter. If a jam occurred, it could create quite a mess in a hurry.
