A mechanical computer is a computer built from mechanical components such as levers and gears rather than electronic components. The most common examples are adding machines and mechanical counters , which use the turning of gears to increment output displays.
The Z2 was one of the earliest examples of an electric operated digital computer built with electromechanical relays and was created by civil engineer Konrad Zuse in 1940 in Germany. It was an improvement on his earlier, mechanical Z1 ; although it used the same mechanical memory , it replaced the arithmetic and control logic with electrical ...

The first digital electronic computer was developed in the period April 1936 - June 1939, in the IBM Patent Department, Endicott, New York by Arthur Halsey Dickinson. [35] [36] [37] In this computer IBM introduced, a calculating device with a keyboard, processor and electronic output (display). The competitor to IBM was the digital electronic ...
It was the industry’s largest electromechanical calculator. [10] The enclosure for the Mark I was designed by futuristic American industrial designer Norman Bel Geddes at IBM's expense. Aiken was annoyed that the cost ($50,000 or more according to Grace Hopper) was not used to build additional computer equipment. [11]

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] Program code was stored on ...
The IBM Selective Sequence Electronic Calculator (SSEC) was an electromechanical computer built by IBM. Its design was started in late 1944 and it operated from January 1948 to August 1952. Its design was started in late 1944 and it operated from January 1948 to August 1952.
