UNIVAC 1004

The UNIVAC 1004 was a plug-board programmed punched card data processing system, introduced in 1962, by UNIVAC. Total memory was 961 characters (6 bits) of core memory. Peripherals were a card reader (400 cards/minute), a card punch (200 cards/minute) using proprietary 90-column, round-hole cards or IBM-compatible, 80-column cards, a drum printer (400 lines/minute) and a Uniservo tape drive. The 1004 was also supported as a remote card reader & printer via synchronous communication services. A U.S. Navy (Weapons Station, Concord) 1004 was dedicated to printing from tape as a means of offloading the task from their Solid State 80 mainframe, which produced the tapes.
