There is a cadre of American officers composed entirely of a whole department of the Electrical Till Corporation. One day, early in 1942, they put their white shirts and blue suits into mothballs, donned Army uniforms, and climbed on ships to Brisbane. Their ringleader is a guy named Lieutenant Colonel Comstock, and he has gotten the whole code-breaking process totally automated. The cards punched by the Aussie girls come into the machine room stacked into ingots which are fed through the machines. Decrypts fly out of a line printer on the other end and are taken off to another hut where American nisei, and some white men trained in Nipponese, translate them.
