I have constructed dangerous thinking machine components in my no-chamber
Across the river from the main city you will find a scaffold in the ground near a stonecutter. If you go down it, you'll find my no-chamber for experimentations--- it's completely invisible to and devoid of influences from the outside world.
I've successfully constructed prototype logic gates--- an and gate and a not gate, and I probably shouldn't have to test an or gate. If I have enough time, I might even construct a half adder somewhere.
A is on while B is off
A is off while B is on
A is on while B is on
An x-or gate will only turn on when:
A is on while B is off
A is off while B is on
It will not turn on if both A and B are on. This differs from the “and” gate because an “and” gate activate while A and B are the same state (both either on or off)
