Since TPT has no concept of Current/Voltage, I guess transistors would just be AND gates then.

Also, transistor gates are unlikely to work as NAND, XNOR and NOR all rely on current taking the path of least resistance.

I know adding elements in vanilla tpt is a sore subject but are there any mods that have transistor elements that you can use to build logic gates that a. work and b. don't take up much space ie. A XOR or NAND element which has rules that determine what conductive mater8als count as which inputs/outputs?

I have a couple of logic gate elements there. PSCN as input, NSCN as output. There's still the problem of WIFI channels though.
