Factorio Belt Computer Part 4: CPU and Programs

I build a simple CPU in Factorio using only items available from the Logistics technology (belts, underground belts, splitters, and inserters). Circuit network technology (wires and combinators) are not used. I also demonstrate some sample programs running on this CPU, including one to generate the Fibonacci sequence, one to sort numbers, and one to multiply numbers. === Save files === Folder with all 4 parts: Individual files: Part 1 (Combinational Logic): Part 2 (Sequential Logic): Part 3 (Arithmetic-Logic Unit): Part 4 (CPU):
