I can hear the younger crowd asking, "What's a card reader? Some sort of credit card thing?"

Kind of depressing: I've *used* Hollerith cards (albeit only once or twice, and only in connection with a system that had no batch-submit-from-terminal functionality), and most of the programmers I know haven't a clue what a Hollerith card *is.*

On the other hand, one of the churches I bounce around among has a digital organ that's old enough that it *takes* Hollerith cards for the old Allen "Alterable Voices" feature. Although the cards aren't encoded in Hollerith code, but rather in something denser, that's specialized for squeezing a half-cycle sample into 80 columns.
