Electronic Discrete Variable Automatic Computer (EDVAC)














John Mauchly and J.P. Eckert also proposed the development of EDVAC. The conceptual design for EDVAC electronic computer to use the stored program concept introduced by John Von Neumann. Unlike the ENIAC, it used binary number rather than decimal. The University of Pennsylvania built the EDVAC for the U.S. Army’s Ballistics Research Laboratory at the Aberdeen Proving Ground. EDVAC had almost 6000 vacuum tubes and 12000 diodes. It consumed 56kW of power. It covered 490 feet square of floor and weighed 7850kg.
