On the Subject of the Fractionated Morse CM
A machine that knows no bounds when it comes to ciphers.
Create a key using the keyword on screen 1 and the Boolean Expression on screen A. Then place the following underneath the key:
.........---------xxxxxxxx
...---xxx...---xxx...---xx
.-x.-x.-x.-x.-x.-x.-x.-x.-
This will be referred to as the Fractionated Morse Key.
Concatenate the encrypted word with the letters shown on screen 2 (if there are any) in that order. For each letter of the string you just created, convert them into a series of dots, dashes, and xs using the Fractionated Morse Key. Read it as Morse Code treating the Xs as spaces between the letters. You should now have a decrypted word.
Example
Encrypted Word: FCTL
Screen 2: SG
Fractionated Morse Key: FALSEBCDGHIJKMNOPQRTUVWXYZ
F → ...
C → .x.
T → x.-
L → ..x
S → .-.
G → .xx
....x.x.-..x.-..xx → HELL
Decrypted Word: HELL
