content: The EDVAC (Electronic Discrete Variable Automatic Computer) was a mainframe computer designed and built at the Moore School of Electrical Engineering of the University of Pennsylvania for the Ballistics Research Laboratory at the Aberdeen Proving Ground. It was the successor to the ENIAC. Discussed from the mid-1940s, it was transferred ti the Ballistics Research Laboratory in 1949, became fully functional in 1952, and was finally shut off in 1962. In that last year, this small circuit from the EDVAC was transferred to the Smithsonian collections. It has a metal frame, four vacuum tubes, and miscellaneous other circuitry.
