Multics encouraged the development of a new user interface, the video display terminal. Video Display TerminalsBy 1964, MIT, Bell Laboratories and General Electric had collaborated to create a computer system called Multics a time sharing, multi-user system. The emerging electric typewriter further improved the technological marriage between the typewriter and the computer. In 1948, the Binac computer used an electromechanically controlled typewriter to both input data directly onto magnetic tape (for feeding the computer data) and to print results. In 1946, the Eniac computer used a punched card reader as its input and output device.
Keypunches were the basis of early adding machines and IBM was selling over one million dollars worth of adding machines in 1931.Įarly computer keyboards were first adapted from the punch card and teletype technologies. Elsewhere, punched card systems were combined with typewriters to create what was called keypunches. The teletype machine, introduced in the 1930s, combined the technology of the typewriter (used as an input and a printing device) with the telegraph. Inventions Leading to the Computer KeyboardA few key technological developments created the transition of the typewriter into the computer keyboard. The Remington Company mass marketed the first typewriters starting in 1877. Christopher Latham Sholes patented the typewriter that we commonly use today in 1868. The invention of the modern computer keyboard began with the invention of the typewriter.
