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:

This will be referred to as the Condi Key.

Convert the letter on screen 2 to a Value via the Value Table. This is your starting offset.
