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.
Konrad Zuse was born in Berlin on 22 June 1910. [21] In 1912, his family moved to East Prussian Braunsberg (now Braniewo in Poland), where his father was a postal clerk.Zuse attended the Collegium Hosianum in Braunsberg, and in 1923, the family moved to Hoyerswerda, where he passed his Abitur in 1928, qualifying him to enter university.
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 ]
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 ...
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. In the Z2, he replaced the arithmetic and control logic with 600 electrical relay circuits, weighing over 600 ...

Zuse was a schoolmate and co-worker of Schreyer, who advised Zuse on relays. Subsequently, Zuse built the Z3 computer, integrating relays as arithmetic logic unit . The Z3 computer was completed in 1941 and used 2,600 relays, with the distinction of being the first computer that was fully operational, controlled entirely automatically, and ...
