Cliff Horrocks, who died in the early hours on the 1st May at the age of 90, was a highly respected electronics engineer who was instrumental in the successful construction of the rebuild of the Colossus computer at TNMOC on Bletchley Park.... ...Cliff retired as Senior Electronics Engineer from FCO in 1980 and the majority of his work there remains classified, however it is known that Cliff’s work on the six tone Piccolo transmission system was instrumental in its success and it was Piccolo that was the only means of communications back to the UK from the Falklands during the conflict.... Cliff Horrocks 1921-2012 (I believe there is a Piccolo at Bletchley in the Diplomatic Wireless room)
