Oh yes, I've seen other people do similar things with 8-bit CPUs on a bunch of breadboards which is awesome, maybe I'll attempt that another time!

I did suffer a different form of pain with trying to implement all the gates together in a GP programming language - that was probably a bad idea in hindsight!

I have approached it in two different ways. One was with discrete hardware on breadboards. The other was with VHDL and an FPGA. Out of the two I would say the breadboard method was the most satisfying because at the end you can show it off as wizardry to the two people or maybe three people in your life who love you enough to be bothered by it.
