    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.

    Matthew
