label: Description (Brief)
content: The Univac 1004 Card Processor was designed and developed in the 1960's. Its physical size and processor speed along with its peripheral devices (card reader, printer and card punch) was at the time, a versatile computer product. In addition to these peripherals, it had 931 bytes of memory. The Univac 1004 was initially programmed via a Plugboard. Consequently, each application required a different plugboard. Or alterations to similar programs could be made to the same plugboard or program, by turning alteration switches on or off. Over it's lifetime, additional peripherals, magnetic tapes, paper tape and a DLT (data line terminal) were added.
label: Description (Brief)
content: Univac redesigned the basic Univac 1004 by adding extra memory to the processor, and by using a permanently wired plugboard to allow the Univac 1004 to be programmed using internally stored programs. This redesigned plugboard included hardware logic and circuitry as well as a program to do this. This plugboard was then covered and would remain permanently on the 1004. Univac called this system the Univac 1005.
label: Description (Brief)
content: The Univac 1004 served many functions. Because of its excellent speed in card reading, and printing speeds with excellent print quality, it was used on many Univac medium to large mainframe systems as an online device. With the addition of the DLT, it was also used as a remote peripheral device. Besides being a business computer, the Univac 1004 was used by the Army in the field during the Vietnam War, mounted inside trucks and also aboard ships. The Univac 1004 was the last Univac System to be programmed via Plugboard.
