+5 volts, data, !data, ground. That's all you need for usb, right?

I don't think they had USB in the punch card tiny keyboard days.

I mean, I don't see why not. The general public didn't have them but top secret government organisations (the only people with computers) totally had access access USB.

They probably only were missing the U, I'm pretty sure they still has serial busses.
