In addition to the rare "Interpreter punch", there was also a quite a bit
less rare variant, the "Verifier". It would READ a card as the operator
typed. If the card and keyboard didn't match, (IIRC after a couple of
tries) it would put a notch in the top of the card at the point of
discrepancy. If everything matched, it would put a notch in the side of
the card, as testimony to it having been checked.

How many remember how service bureaus would CHEAT?

Who is collecting EAM equipment?
