| Description |
M-9 Bombe Checking Machine Since the Allies did not know the German's daily rotor settings, several Bombes worked on the same message. Each Bombe tested a different set of wheel orders. The Bombes usually found two sets of possible rotor settings on each run, but only one setting on one Bombe was the correct wheel order and rotor setting used by the Germans for that day. After the Bombe completed a run, a WAVE supervisor checked the printed results on this M-9 machine. She checked each result looking for the correct one. Once she found the results, she used the M-9 to fill in any missing plugboard positions. The Bombes could find only a portion of the Stecker (plugboard) positions.
