Visit to Bletchley Park and South Coast - Friday 19th August 2011

13. the back of the Bombe - no electronics here. This device is purely electro-mechanical driven by the huge electric motor you see at the bottom of the picture. The "Colossus" which followed, was even more complex because it was decoding the German naval machine which had four rotors instead of the usual three. It was the first computer in the world. We saw it but I didn't manage to get a photo of it. (I have to admit it was all a bit over my head - but then I'm not a genius like Turing was!)
