I'm working on a binary to decimal converter in Minecraft. I have the decimal part down, and made a calculator for that, but it isn't much use unless I can convert it to base 10. However, I don't recall coming across any latches that will only turn on if two power sources are on, and not any time else. If anyone has an answer to this, that'd be great.
Sorry, what I'm looking for is a reversed AND gate, if that makes any sense.
It doesn't. It sounds like you need a normal AND gate with multiple inputs. AND together the two input you're interested in along with the negation of any inputs you want to be off. So if you have three inputs, A, B and C and you want to trigger when only A and B are on, you'd AND together all of A, B, ~C.
Now if you want it when ANY two inputs are on, you've got a bit more of a challenge.
