National Museum of Computing Invites Public to Try Their Luck Against Old Cipher Tech

Members of the public are being challenged to take on a rebuilt version of Colossus, the world's first programmable digital computer. The Cipher Challenge will take two groups of amateur code breakers and pit them against one of the original Lorenz cipher machine used by the German High Command during World War II. - Slashdot

WW2 cipher breaking machine Colossus will be exhibited at new National Museum of Computing, Bletchley Park. He contributed to the effort to solve Tunny, a German teleprinter cipher. A new museum that explores the history of computing will have its official opening today at Bletchley Park. UK computer history gets new home.
