In "The Imitation Game", alan turing named the machine he invented "Christopher", but in the real prototype, the machine invented by alan turing was called bombe, and "Christopher" came from alan turing's first love name.
Bombe is an advanced computer developed by Alan Turing during World War II, mainly used for code breaking. Bombe evolved into a large family. The Bombe series was manufactured by the British Tabulating Machine Company (BTW). After the machine was introduced to the United States, another more famous tabulating machine and punched card machine company also began to produce the Bombe. This was IBM, which had not yet become Big Blue at the time. .
Bombe's structure
Bombe is made of a reinforced laminated plastic. Through 158 trillion password combinations, this decoder can uncover seemingly random but actually complex codes that change every day. The Nazi "mystery" code. The decoding machine looks like a typewriter and uses three or four rotating wheels to piece together letters. Normally, it is impossible for operators to see the internal structure of the "Turing dessert" decoder.
The wall on the right is actually a hinged door filled with electronic circuits, and the wall on the left is the mechanical part of the "Turing dessert". The colorful squares are resistors, and the circles of red wire are circuits.
