On our machine we punched by hand the binary instructions directly onto 80-column punch cards, one bit at a time.i.e., we punched the entire 32-bit instruction onto a row of a card, by hand.
To correct an instruction, we'd get one of the chips and push it into a hole
in a card. Then we'd reproduce the card on a gang punch.
