retro-g15

The Bendix G-15 was a mid-1950s, binary, vacuum-tube, drum-memory computer system. The system was designed by Harry Huskey for Bendix during 1952-1953, while at Wayne State University in Detroit, Michigan. It was first available to customers as the G-15A in 1956. The better-known G-15D was released in 1957. Huskey had worked on Alan Turing's ACE computer and its prototype, the Pilot Ace, at the National Physical Laboratory in England during 1946-1947. The design of the G-15 was heavily influenced by the Pilot ACE, especially in its bit-serial operation, source-to-destination command structure, and its implementation of memory and registers as recirculating delay lines. The delay lines were implemented using the rotating magnetic drum rather than the mercury-filled tubes of the Pilot ACE. The G-15 was an unusually small and inexpensive computer system for its day. The basic configuration consisted of a single cabinet and a modified IBM Model B electric typewriter. The cabinet was 61 inches high by 27 inches wide by 32 inches deep (155 x 69 x 81cm), weighing 950 pounds (430kg) -- about the size of a home refrigerator. It ran on standard U.S. 110-volt power, drew 38 amps (about 3KW RMS), and dissipated 14,300 BTU/hour of heat. It used approximately 450 vacuum tubes and 3000 germanium diodes. retro-g15 is the open-source project pkimpel/retro-g15 (https://github.com/pkimpel/retro-g15) by pkimpel, released under MIT.
