Mux, DMux and another register

A project log for LLTP - Light Logic Transistorless Processor

My attempt to create a CPU/MCU without transistors or relays

Now for the next step. I want to start the construction of a 4 to 1 Mux, a 1 to 4 DMux and another register. These steps will allow the LLTP to feed a value back to the Adder and in turn perform a counting function. I will still use toggle switches to enable the registers and select the Mux and DMux and once happy with the result I will forge ahead with the sequencer and experiment with program instructions. The Logisim circuit is for one bit.
