Nice idea! Did you already calculate how many gates and flip flops are needed? Next step: only use transistors. only vacuum tubes, only relays, reading the HP-35 ROM code from hard coded 768x10 bit magnetic core memory. I can see the Zuse Alejandro ZA3, the first relays computer with trigonometric and exponential functions. Smile
