The steam-powered automatic flute described by the Book of Ingenious Devices (850) by the Persian-Baghdadi Banū Mūsā brothers may have been the first programmable device. [10] Other early mechanical devices used to perform one or another type of calculations include the planisphere and other mechanical computing devices invented by Al-Biruni ...
The category of early computers contains the computer systems made in the early era (i.e., the era in modern computer history defined as the period from the late 1930s to the early 1960s) utilizing mechanical, vacuum tube, discrete transistor, or other pre-integrated circuit technology.

This is a list of early microcomputers sold to hobbyists and developers. These microcomputers were often sold as " DIY " kits or pre-built machines in relatively small numbers in the mid-1970s. These systems were primarily used for teaching the use of microprocessors and supporting peripheral devices, and unlike home computers were rarely used ...
Three brothers who wrote the Book of Ingenious Devices, describing what appears to be the first programmable machine, an automatic flute player. [8] 1960–1964 Baran, Paul: One of two independent inventors of the concept of digital packet switching used in modern computer networking including the Internet.
Heath Robinson is the name of a British cartoonist known for drawings of comical machines, like the American Rube Goldberg. Two later machines in the series were named after London stores with 'Robinson' in their names. 1943 Sep United States: Williams and Stibitz completed the 'Relay Interpolator', later called the 'Model II Relay Calculator ...
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 ...
A vacuum-tube computer, now termed a first-generation computer, is a computer that uses vacuum tubes for logic circuitry. While the history of mechanical aids to computation goes back centuries, if not millennia, the history of vacuum tube computers is confined to the middle of the 20th century. Lee De Forest invented the
Charles Babbage KH FRS (/ ˈ b æ b ɪ dʒ /; 26 December 1791 – 18 October 1871) was an English polymath. [1] A mathematician, philosopher, inventor and mechanical engineer, Babbage originated the concept of a digital programmable computer.
