The TMS 1000 was one of the first commercially available microprocessor-based computers, introduced by Texas Instruments in 1974. It was primarily designed for use in electronic games and simple applications, featuring a 4-bit microprocessor. The TMS 1000 was notable for its affordability and compact size, making it accessible for hobbyists and developers. This early microprocessor was used in various products, including calculators and toys, and laid the groundwork for future developments in computing technology. The TMS 1000's architecture influenced later microprocessors, contributing to the evolution of personal computing and embedded systems in the years that followed.
