the operation of the 421 was directed by the use of a removable control panel and a carriage tape. by means of the control panel, any column of the card could be wired to any print column, by means of a wire link (the end terminals of which were inserted into slots in the control panel). when the control panel wiring was complete, the control panel was inserted into the guides in the machine, and a hand-operated lever moved the control panel so that the wire links made contact with corresponding terminals in the machine.
