To develop the Bob/Ike/Qui Trinary Logic set, we looked at what the AND and OR gates actually did with the numbers in Boolean logic. Let's look at the OR gate first. In this gate, we say that the 1 has dominance. That is to say, output is a 1 anytime a 1 is present. You could say a 1 blocks a 0 in the OR gate. A 0 is only output if there is no 1 present. AND is just the opposite: output is only a 1 if there is no 0 present.
p | q | p BOB q --------------- 2 | 2 | 2 2 | 1 | 2 2 | 0 | 2 1 | 2 | 2 1 | 1 | 1 1 | 0 | 1 0 | 2 | 2 0 | 1 | 1 0 | 0 | 0
A bit discouraged, we decided to forget the whole theory of merely copying Boolean logic and came up with a new idea, based more on getting the half-adder to work.
