The IBM 519 Document-Originating Machine, introduced in 1946, was the last in a series of unit record machines designed for automated preparation of punched cards. Others in the series included the IBM 513 & IBM 514 Reproducing Punch.
The 519, which was "state of the art for the time",[1] could:
- reproduce all or parts of the information on a set of cards
- "gangpunch" - copy information from a master card into the following detail cards
- print up to eight digits on the end of a card
- compare two decks of cards
- "summary punch" — create punch cards containing summary information provided by a connected accounting machine, such as totals from a group of processed cards
- "mark sense" — detect marks made with an electrographic pencil in designated locations on a punched card and then punch holes corresponding to those marks into the card
- number cards consecutively (an optional feature)
The reproducing, gangpunching, summary punching, and comparing features of the IBM 519 are very similar to those of the IBM 513 and IBM 514.
