quad exclusive-OR gates

This is a redo of my earlier XOR module.

This one is also based entirely on the 4070 quad exclusive-OR IC only this time I squeezed all 8x inputs onto the front panel so each gate has its own pair of inputs instead of sharing with neighbours.
This time all inputs are comparators, too, instead of the little inverting mosfet circuit I thought was clever at the time but didn't work quite as well as an opamp comparator and added more parts to the BOM.

Inputs C, E, and G are normalled to the output of the gate above so you can chain gates to get a 3, 4, or 5 input XOR.

I had to get a little creative placing the power connector. Regrettably one corner of the power plug will overhang the righthand side of the panel by almost 1mm. Should be okay next to most modules but if mounting in the rightmost position of your case there's a chance it'll hit the side and leave a small gap, oops!
I may fix this in future, but for now beware!
