The Chilton Atlas was ordered in September 1961. Installation and commissioning started in June 1964 and an at risk service started in October 1964. The machine was formally handed over in May 1965 and the acceptance period began. By February 1966 it was in full 3-shift operation. Formal acceptance took place in May 1966.

This section gives details of the hardware and architecture of both the Atlas I and Atlas II computers together with some history of Ferranti, the company that manufactured the six Atlas computers.
