The first stored program computer, built in 1952. Derived from electron discrete variable automatic compiler.

EDVAC

(Electronic Discrete Variable Automatic Computer) The successor to ENIAC, EDVAC was designed by J. Presper Eckert and John Mauchly at the University of Pennsylvania in the 1940s. Although it was the first stored program computer, it did not become operational until 1952, two years after SEAC, which was based on EDVAC designs.

EDVAC was an arithmetic-only computer working with binary numbers rather than the decimal operations of ENIAC. It had 1K 44-bit words of delay line memory. See ENIAC, SEAC, early memory and early computers.

While Turing remained away at Cambridge, at least five other teams in the UK - and many more in America - set to work developing and building stored-program universal computers similar to that outlined in Turing's Edvac Report.
But because the Mark I was an electromechanical device orders of magnitude slower than its younger electronic cousins the ENIAC and EDVAC, and because Aiken himself was often perceived as being out of touch with later developments in computing, his legacy is ofte n misunderstood and underrepresented.
