My (cleared) paper revealing the Colossus was given at the splendid Los Alamos conference in June 1976 – see
<a href="https://computerhistory.org/blog/computings-woodstock/">https://computerhistory.org/blog/computings-woodstock/</a>. (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” - <a href="http://homepages.cs.ncl.ac.uk/brian.randell/Papers-Books/126.pdf">

<p class="MsoNormal" style="margin-left:36.0pt">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?<o:p></o:p></p>
