English Electric and Elliott's were two of the UK's early computer companies. They merged with GEC in 1969 to form Marconi Elliott Computer Systems(MECS) Ltd with the plan to develop three systems alpha (became the GEC 2050), beta (became the GEC 4000 range) and gamma (never developed).

The first machine was the MECS 2050, launched in 1970 and later renamed the GEC 2050. It provided the user with a powerful, low cost, real-time computing system with a high degree of reliability. This was the reason it was adopted by Atlas and Rutherford as the standard Remote Job Entry Station.

>Michael Melliar-Smith was the principal designer for the GEC 4000 series. He worked at GEC from 1964 to 1973.
