MyNOR: Single board computer that uses a single NOR gate as its ALU
I wonder how this ALU works. From what I remember ALUs use lot of XOR gates because an adder is simply a network of XOR gates with carry propagation.How could a NOR gate do one bit addition?Add two bits  ...  XOR  ...  NOR0 + 0 = 0...........0...........10 + 1 = 1...........1...........01 + 0 = 1...........1...........01 + 1 = 0...........0...........0
