And some of us go back to when computers were roomsized, used vacuum tubes
and 80 column cards (row binary for program decks!) or paper tape, and 4k
words was a LOT of memory!

Before 300 baud modems (the ones in the nice wooden boxes with acoustic
couplers for a handset) there was the IBM transceiving card punch that
read cards, ran the data through a rack of stuff and a dedicated line to
another rack of stuff and the companion which reproduced the cards at the
far end.
