The IBM 1402 was a high speed card reader/punch introduced on October 5, 1959 as a peripheral input/output device for the IBM 1401 computer using standard IBM 80 column punch cards. Originally available in six models, the 1402 was used with other computers of the IBM 1400 series, IBM 7000 series between 1959 and 1962, while also being modified into the IBM 1622 Card Read-Punch for 1959s IBM 1620 system. The reader and punch feeds were separate and functionally independent, with individual switches, lights, checking circuits, buffer storage, and instruction codes. Under program control, up to 250 cards per minute can be read and 125 per minute punched. Reading, punching, and processing can occur simultaneously because of individual buffer storage. This model represents the original 1402 card reader used with the IBM 1401 computer system.
