Dr. CockroachThe Not gate and Nand gate works great. Now onward to the Nor gate. The Nor gate will be simpler than the Nand as all I have to do is reverse the two 1N914 diodes and remove their 910 Ohm resistor. That will give me ALL the logic gates I will ever need using scrap parts without ever using a single transistor, relay or vacuum tube.
Nor Gate ? No Problem

Using a LED/LDR pair to form inverting Photonic logic gates. The entire Boolean logic set handled by resistors and diodes! Who'd'a thunk
