Hi Joris:
I was shown the photographs, and given permission to interview the developers, in mid-1975. A set of photographs, and a single-page description, were released to the Public Record Office in 1975. My (cleared) paper revealing the Colossus was given at the splendid Los Alamos conference in June 1976 – see https://computerhistory.org/blog/computings-woodstock/. (I had previously, in 1972, published such few facts as I could discover about the project in my 1972 paper “On Alan Turing and the Origins of Computers” - http://homepages.cs.ncl.ac.uk/brian.randell/Papers-Books/126.pdf.)
Cheers
Brian Randell

Hi,
Any ideas on this puzzling sentence in the press release? “The Colossus computer was created during the Second World War […] but its existence was only revealed in the early 2000s after six decades of secrecy.” As far as I know the existence of Colossus has in no way been a mystery at least since the early 1970s, right?
Best
