NOR Gate circuit - Can it be built with floating inputs

Okay - so what I need to do now is come up with a set of logical operations that both A and B go through to deliver the desired outputs at W, X, Y and Z. I'll get back when I have the answer figured out.

Cheers.

That's correct, and the logic functions are really simple. Don't waste too much time on them unless you want the learning experience. We can post them here.
PS The simplest way is probably to use gates in the CD4000 logic family. Keep in mind that you will have to follow each one with a level translator, which will generally also be a logical inverter.

Roff - thanks. For now I am going to go without a brake. I completed the circuit (version 2) and thus far it seems to work fine.

I will revisit the brake function at a later date and learn smething about the logic family that you have suggested.

Again thanks for all of your help
