The nor gate (like nand) is a universal gate. You can implement all the other gate with a combination of nor gate. See https://en.m.wikipedia.org/wiki/NOR_logic#XOR for example.

Not with a 'single NOR gate'.

Yes .. if you feed its output to its input on the next cycle.

Then the ALU includes the sequencer and the microprogram.

Shifts are implemented with look-up tables.

Anyway it's a beautiful work.
