ICL 1906A 26 of 33
Nottingham had one of the early ICL 1906A computers. A block purchase was made of machines for Nottingham, Birmingham, Leeds and Oxford. Our machine had 128k of 24-bit memory, a drum for paging. The machines were ordered before a prototype had been made, so performance characteristics had to be predicted from the design. By this time the Nottingham Cripps Computing Centre was under the directorship of Eric Foxley. The CCC south building was built initially to house the 1906A. The power demands of the machine were enormous; the building was supplied with nearly half a megawatt of power. The air conditioning for the processor was calibrated in tons-of-ice-per-hour. The machine was funded by the Computer Board.
The 1906A had a novel multi-layer design of its cards/platters.
