The ' Our Computer Heritage ' Site, Feb 2012.
Here you’ll find technical information on 90% of the British-designed computers that came onto the market in the period 1950 – 1965. The data, compiled by the Computer Conservation Society, covers the major stored-program electronic digital computers manufactured by six historic UK companies:
Elliott Brothers (London) Ltd.
Ferranti Ltd.
Leo Computers Ltd.
EMI.
English Electric Ltd.
BTM/ICT/ICL.
