A program running in a Kenbak-1 IDE/emulator Kenbakuino, an Arduino-based Kenbak-1 emulator. The Kenbak-1 is considered by the Computer History Museum, [2] the Computer Museum of America [3] and the American Computer Museum [4] to be the world's first "personal computer", [5] invented by John Blankenbaker (born 1929) of Kenbak Corporation in 1970 and first sold in early 1971.

CSIRAC (/ ˈ s aɪ r æ k /; Commonwealth Scientific and Industrial Research Automatic Computer), originally known as CSIR Mk 1, was Australia's first digital computer, and the fifth stored program computer in the world. [1] It is the oldest surviving first-generation electronic computer [2] (the Zuse Z4 at the Deutsches Museum is older, but ...
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
The Ferranti Mark 1, also known as the Manchester Electronic Computer in its sales literature, [1] and thus sometimes called the Manchester Ferranti, was produced by British electrical engineering firm Ferranti Ltd. It was the world's first commercially available electronic general-purpose stored program digital computer. [a]
TI-99/2, [42] a 4K RAM, 32K ROM computer with no color, sound, or joystick port and a Mylar keyboard. TI designed the computer in four and a half months to sell for under $100 and compete with the Sinclair ZX81 and Timex Sinclair 1000. Based on the TMS9995 CPU running at 10.7 MHz and with a built-in RF modulator, performance greatly increased ...
