It features five binary inputs on one side and another set of five binary inputs on the opposite side. A single output lamp is positioned on the guessing side, and clear signs label each section.
On the side without the lamp, you’ll find five levers. These levers define the code or key. The opposite side contains five lettered inputs used to enter the code that was set earlier.
There are 31 possible key combinations, and each attempt generally includes about a one‑second processing delay.
Oh also, the logic is mainly just XOR gates with all the outputs OR'd and then NOT'd.
On the side labeled “Set the key”, you flip the levers to define the code or key.
Then, on the opposite side marked “Enter the key”, you adjust its five levers to match the configuration set earlier.To check whether your entered key is correct, simply look at the output lamp.
If it lights up, the code you entered matches the one that was set.
