IBM 514

From Wikipedia, the free encyclopedia

The IBM 514 Reproducing Punch (photo) was a card punching machine developed by IBM. The 514 was announced in 1949, withdrawn in 1978. The machine could perform these functions:

Reproducing all or part of the data on a deck of punched cards.
Gang punching -- copying punched information from a master card.
Summary punching -- punching a total or new balance card amounts which have been accumulated in the accounting machine.
Mark sensing -- the operation by which information recorded in the form of pencil marks on a card is turned into punches on the cards.

Mark sensing allowed a person to enter data to be used in punched-card data processing without using a keypunch machine. It was used for tasks like recording long distance calls or meter readings.
