- The page labels its sample key sheet fictional while modeling the Army/Air Force routine it says was used from May 1940.
Field notes
The page exposes a keyboard-and-tape interface, rotor positions, ring settings, reflector choice, and a plugboard with up to ten cable pairs. Users can encode a whole message, reset settings, or copy a link to a configuration. Its walkthrough traces the signal through the plugboard, three rotors, reflector, and return path, while a separate rotor section lets readers step a wheel and inspect a contact. The sample key sheet is identified as fictional.
