I suspect the world would be better if that percentage were even greater.
8080 bottles of beer…
Okay, not 8080 bottles, but 99 bottles of beer anyway…

Wow!
I watched as you took this project on and I am impressed with your technical chops.
I’d love to know a bit more about your implementation of the processor emulator. Even a high level discussion.
I never took CS type of courses and have taught myself. My attempts at emulators have always hit a mire because of the structure I used. My latest is an HP-35 emulator written in Processing.
Anyway, I’d love to see how you structured the code to handle the opcodes and their related procedures.
