The EDVAC as installed in Building 328 at the Ballistic Research Laboratory. EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest electronic computers. It was built by Moore School of Electrical Engineering at the University of Pennsylvania. [1] [2]: 626–628 Along with ORDVAC, it was a successor to the ENIAC.
By the spring of 1946, Eckert and Mauchly had procured a U.S. Army contract for the University of Pennsylvania and were already designing the EDVAC – the successor machine to the ENIAC – at the university's Moore School of Electrical Engineering. However, new university policies that would have forced Eckert and Mauchly to sign over ...
Theory and Techniques for Design of Electronic Digital Computers (popularly called the "Moore School Lectures") was a course in the construction of electronic digital computers held at the University of Pennsylvania's Moore School of Electrical Engineering between July 8, 1946, and August 30, 1946, and was the first time any computer topics had ever been taught to an assemblage of people.
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
Eckert, a co-inventor of the ENIAC, discusses its development at the University of Pennsylvania's Moore School of Electrical Engineering; describes difficulties in securing patent rights for the ENIAC and the problems posed by the circulation of John von Neumann's 1945 First Draft of the Report on EDVAC, which placed the ENIAC inventions in the ...
1 It used 5,000 vacuum tubes and 1,500 crystal diodes Ferranti Mark 1: 1951 9: First commercially available computer, based on Manchester Mark 1. EDVAC: 1951 1 The successor to ENIAC, and also built by the University of Pennsylvania's Moore School of Electrical Engineering for the U.S. Army's Ballistic Research Laboratory. One of the first ...
Samuel N. Alexander with SEAC Title page of the First Draft of a Report on the EDVAC with Alexander's signature. Samuel Nathan Alexander (February 22, 1910 in Wharton, Texas – December 9, 1967 in Chevy Chase, Maryland) was an American computer pioneer who developed SEAC, one of the earliest computers.
1) Goldstine's job was NOT the secuity officer of the ENIAC project. He was a US Army Captain who oversaw the construction contract. He was also instrumental in getting the project funded. There are many amusing stories about it. 2) I doubt anyone knows whether von Neumann wrote the report on the train or after he got to Los Alamos.
