Installing the magnetic drum in 1954 opened the way to develop a control program for running programs dealing with matrices. Following urging by J. M. Hahn [13] [14] of the British Aircraft Corporation, [15] Brian W. Munday developed General Interpretive Programme (GIP), which required only simple codewords to run a collection of programs called "bricks".
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 $184,600 in 2024 [4]).
Elektro was on exhibit at the 1939 New York World's Fair and was joined at that fair in 1940, with "Sparko", a robot dog that could bark, sit, and beg to humans.. Several minutes of color sound footage of Elektro in action can be seen at 33:55 in the movie, The Middleton Family at the New York World's Fair, a fully-produced hour-long movie made by Westinghouse, which showcased the Westinghouse ...
