On initial power up, it defaults to an Enigma M4, with reflector B thin, Greek wheel Beta, and rotors 1,2,3, set to A, no plugs connected on the plug board. The plugboard is at the bottom, the keyboard is just above it. In the center section the lamp field is visible and the rotors are at the top.
Care was taken to ensure compatibility with the operation of enigma machines and quirks such as double stepping of the middle rotor were implemented. There is a printer tape running in between the lamp field and the rotors.
Modifying the machine settings is done by dragging rings, touching plugs, operating a rotary wheel, the use of menus was mostly avoided to help keep the realistic feeling of operating the machine.
