The D37D Minuteman III flight computer was initially supplied with the LGM-30G missile, as part of the NS-20 navigation system. The NS-20 D37D flight computer is a miniaturized general purpose (serial transmission) digital computer. The new NS-50 missile guidance computer (MGC) is built around a 16-bit high-speed microprocessor chip set.
A second application was a transistorized digital computer to be used in a Navy track-while-scan shipboard radar system. Several models were completed: TRADIC Phase One computer, Flyable TRADIC, Leprechaun (using germanium alloy junction transistors in 1956) and XMH-3 TRADIC. TRADIC Phase One was developed to explore the feasibility, in the ...
It was the world's first commercially available electronic general-purpose stored program digital computer. [ a ] Although preceded as a commercial digital computer by the BINAC and the Z4 , the Z4 was electromechanical and lacked software programmability, while BINAC never operated successfully after delivery.
PDP-1 PDP-6 PDP-7 PDP-8/e PDP-11/40 PDP-12 PDP-15 (partial) PDP-15 graphics terminal with light pen and digitizing tablet. Programmed Data Processor (PDP), referred to by some customers, media and authors as "Programmable Data Processor," [1] [2] [3] is a term used by the Digital Equipment Corporation from 1957 to 1990 for several lines of minicomputers.
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.
An open PDP-8/E with its logic modules behind the front panel and one dual TU56 DECtape drive at the top A "Straight-8" running at the Stuttgart Computer Museum. The earliest PDP-8 model, informally known as a "Straight-8", was introduced on 22 March 1965 priced at $18,500 [3] (equivalent to about $178,900 in 2023 [4]).
The Z3 was a German electromechanical computer designed by Konrad Zuse in 1938, and completed in 1941. It was the world's first working programmable, fully automatic digital computer. [3] The Z3 was built with 2,600 relays, implementing a 22-bit word length that operated at a clock frequency of about 5–10 Hz. [1] Program code was stored on ...
