Enigma Machine, I need help!

[sparkz_alot]

While Larz is working on that, I'll point out that the Enigma machines had no numbers or punctuation (including 'space' and 'period'). The letter 'X' was often used in place of a period and as a 'filler'. The keyboard looked like:

Q W E R T Z U I O
A S D F G H J K
P Y X C V B N M L

The message was entered as an unbroken string of letters, so a sentence like "Pizza party at 1 o'clock." would be entered as "PIZZAPARTYATONEOCLOCKX". Say the encoded string was "ABXDGPRMWQCZSLZPEMVTHJ", this message would be sent via morse code, either as 4 or 5 letter 'words', i.e.: "ABXDG PRMWQ CZSLZ PEMVT HJXXX" (note how last word is padded). At the receiving end, the message is again entered into an Enigma machine with the exact same settings as one long string of letters which results in the decoded message.  Afterwards, both machines are returned to the days default settings, to await the next message.

I mention this because if you include numbers or punctuation in your message you throw off the 'rotors' limit of 26 and the message will encode/decode incorrectly.

I also seem to recall reading some time ago that when the 3rd rotor (far left) initially tripped, it would set rotor 2 back 1 position.  As I said, it was some time ago so I would have to try and verify that, or perhaps, you were already aware of it.

Great project as well as a great look into history.
