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 ]
In 1941, he improved on the basic Z2 machine, and built the Z3. On 12 May 1941 Zuse presented the Z3, built in his workshop, to the public. [23]: 425 [28] The Z3 was a binary 22-bit floating-point calculator featuring programmability with loops but without conditional jumps, with memory and a calculation unit based on telephone relays. The ...

The Z4 was arguably the world's first commercial digital computer, and is the oldest surviving programmable computer. [1]: 1028 It was designed, and manufactured by early computer scientist Konrad Zuse's company Zuse Apparatebau, for an order placed by Henschel & Son, in 1942; though only partially assembled in Berlin, then completed in Göttingen in the Third Reich in April 1945, [2] but not ...
z3 The Z2 was an electromechanical (mechanical and relay-based) digital computer that was completed by Konrad Zuse in 1940. [ 1 ] [ 2 ] [ 3 ] It was an improvement on the Z1 Zuse built in his parents' home, which used the same mechanical memory .
The Z1 was a motor-driven mechanical computer designed by German inventor Konrad Zuse from 1936 to 1937, which he built in his parents' home from 1936 to 1938. [1] [2] It was a binary, electrically driven, mechanical calculator, with limited programmability, reading instructions from punched celluloid film.
This progression, or flow, from machine to machine was often planned and documented with detailed flowcharts that used standardized symbols for documents and the various machine functions. [6] All but the earliest machines had high-speed mechanical feeders to process cards at rates from around 100 to 2,000 per minute, sensing punched holes with ...
The Jaeger Machine Company Office Building is a historic building in the Arena District neighborhood of Columbus, Ohio. It was listed on the National Register of Historic Places in 1983. [1] [2] The two-story concrete building was constructed in 1936. It was designed simply and affordably, but with Art Deco features for a modern design.
