ECKERT, Presper J. & MAUCHLY, John W.
Automatic High-Speed Computing: A Progress Report on the EDVAC. Report of work under contract no. W-670-ORD-4926 supplement no. 4 between Ordnance Department, U.S. Army and University of Pennsylvania, Moore School of Electrical Engieering.Pensylvania: Moore School of Electrical Engineering, September 30, 1945. First edition, first issue.
The extremely rare first technical report on the EDVAC - the first general-purpose electronic digital stored-program computer to be designed. This classified report was issued in just 50 numbered copies and is much rarer than Von Neumann's nontechnical June-report, i.e., First Draft of a Report of the EDVAC which was not classified and distributed widely and "contained little engineering detail, in particular concerning electronics" (Copeland, The Essential Turing). We know of no other copy of this report having appeared on the market and can locate just three copies worldwide: Smithsonian, Penn, and UCLA. "The modem electronic computer had its origins in the work of J. Presper Eckert and John Mauchly and their colleagues at the Moore School of Electrical Engineering of the University of Pennsylvania in the years between 1942 and 1946... During those years the group at the Moore School designed and built the ENIAC, the first large scale general purpose electronic computer. Also during those years their design of the EDVAC introduced the revolutionary idea of the modem stored program electronic computer. "In early 1944, after the design phase of the ENIAC was complete, some members of the group at the Moore School started to work on the design of a successor machine which came to be known as the EDVAC (Electronic Discrete Variable Computer). The principal shortcomings of the ENIAC were recognized to be inadequate storage and the difficulty of settting up new problems, i.e. the difficulty of programming. On January 29, 1944 Eckert wrote a 'preliminary disclosure' in which he … [Click Below for Full Description]
