This is going to be logical and congruent, a breath of fresh air. One odd operator EI (either) and one even AND to produce all existing incongruent combinations of logic (3 true -1 false) and (1 true - 3 false). Rather than four 3 - 1 logic operations required to produce a balanced 2 - 2 output.
EI (either) gates and AND gates can be assigned to their effective circuit topologies.
AND: two switches off = circuit on (EVEN)
EI: two switches on = circuit off (UNEVEN)
The logic needs to produce a balanced output for it to be the simplest two transistor logic. If it is unbalanced 3 -1 logic it can be composed of..
AND * EI (series circuit) = OR
AND + EI (parallel circuit) = AND (legacy)
A lowest common denominator for the system of logic gates, balanced operation (2 true - 2 false).
