Colossus computer
In November 2007, to mark both the end of the work and the start of fundraising (asking for money) they ran a competition. The money would help The National Museum of Computing with a Cipher Competition where the rebuilt Colossus competed with radio amateurs all around the world. The first to hear and decode three messages enciphered would win.  They would be enciphered using the Lorenz SZ42 and transmitted from the radio station in the Heinz Nixdorf MuseumsForum  computer museum in Germany. The competition was easily won by radio amateur Joachim Schüth.  Schüth had gotten ready for the event. He made his own signal processing and code-breaking program using Ada. The Colossus team lost because they wanted to use World War II radios,. They were a day late because of bad radio conditions. The winner's 1.4 GHz laptop, running his own program, took less than a minute to find the settings for all 12 wheels. The German codebreaker said: "My laptop worked on ciphertext at a speed of 1.2 million letters per second—240x faster than Colossus. If you compare the two computers, you could say Colossus had a speed of 5.8 MHz. That is very fast for a computer built in 1944."
