The rebuilt Colossus was last week put to work on intercepted radio messages transmitted by radio amateurs in Paderborn, Germany, which had been scrambled by a machine used by the German high command in wartime.
Pictured is the reconstructed machine, which took 6,000 volunteered man days to rebuild.
