use if words were missing or parts were garbled they couldn't be guessed by trying combinations of other levels. This complexity was helpful to the Japanese because translators often had to wait for other intercepts to build up before they could get a full translation of the first message.
             The construction of the machine was complicated. There were three major components. The first was an electric typewriter, which was used to put information into the machine. The second was the cryptographic assembly consisting of a plugboard, four electric coding rings, wires and switches all sitting on a wooden frame. The third component was a printing unit, which was used to print out the encrypted message. The first typewriter, know as the Alphabetical typewriter, was built to work on roman letters so it was able to encipher English, romaji, and roman letter code texts. The two electric typewriters were then connected to twenty-six wires, which were in turn plugged into a row of sockets, which was known as a plugboard. In between the plugboard of the plain text machine and the cipher text machine were the four coding wheels, which were constantly shifting. The plugboards and the coding wheels were both very important to the success of the machine. They diverted the current !
             that flowed along the connections from the input typewriter to the output typewriter. The diversion was made so that when the "a" key was pressed on the input keyboard, "a" wouldn't be typed on the output keyboard. The coding box also played an important role. If the coding box was not present the plugboard wires would take the electric impulse from one key of the Alphabetical Typewriter and bring it directly to a certain key on the cipher text machine. All of the other wires would also connect the plain text keys to cipher text typebars, which were non-corresponding. Doing this would only produce an elementary cipher, which would be lacking the security needed for the ...
