Solid state 3-tick CCA [improvement]

[Magic :^)]

Well, this kind of addition is kind of applicable to real circuitry, depending on how much of a voltage drop you get across transistors and such before you hit an indeterminate voltage level.

I was messing with a practical implementation of CCA logic a few months ago and the above logisim circuit is what I came up with.
