Plankalkül (German pronunciation: [ˈplaːnkalkyːl]) is a programming language designed for engineering purposes by Konrad Zuse between 1942 and 1945. It was the first high-level programming language to be designed for a computer.
It is now in the Konrad Zuse Museum in Hünfeld, Germany. [47] [48] Memory was halved to 32 words. Power consumption is about 400 W, and weight is about 30 kilograms (66 lb). [49] In 2008, Horst Zuse started a reconstruction of the Z3 by himself. [50] It was presented in 2010 in the Konrad Zuse Museum in Hünfeld. [51] [52]
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 ...
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 Z5 was a computer designed by Konrad Zuse and manufactured by Zuse KG following an order by Ernst Leitz GmbH in Wetzlar in 1950. The computer was delivered in July 1953 [1] and was the first commercial built-to-order mainframe in Germany. The computer was purchased to help with the design of optical lens systems.
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 ...

The Z22 was the seventh computer model Konrad Zuse developed (the first six being the Z1, Z2, Z3, Z4, Z5 and Z11, respectively).One of the early commercial computers, the Z22's design was finished about 1955.
