 Like the Datapoint 2200, it used small-scale integrated transistor–transistor logic instead of a microprocessor.It was marketed as an educational and hobbyist tool, but it was not a commercial success; production ceased shortly after introduction.In late 1972, a French team headed by François Gernelle within a small company, Réalisations & Etudes Electroniqes (R2E), developed and patented a computer based on a microprocessor – the Intel 8008 8-bit microprocessor.
