The first Elliott 152 computer appeared

Elliott Brothers (London) Ltd was an early computer company of the 1950s60s in the United Kingdom. The research laboratories were based at Borehamwood, originally set up in 1946. The first Elliott 152 computer appeared in 1950

It had a multiply time of 60 microseconds and first ran a program in 1950. For comparison, the American Whirlwind real-time computer first ran a program in 1951 and had a multiplication time that varied between 36 and 44 microseconds.

The Elliott 152 employed an anticipation-pulse electrostatic RAM based on the original Williams Tube patent but operating at three times the speed of the Manchester implementation of CRT memory. The 152s plug-in units were based on printed circuits on glass plates, with plated-through holes, deposited resistors, semiconductor diodes and sub-miniature pentodes. This cutting-edge technology unfortunately became a bleeding edge: the 152s reliability left much to be desired and the MRS5 contract was eventually curtailed by the Admiralty.
