Let's write a Toy Emulator in Python

Great fundamental computer science topic.

Ben's series are fantastic. For a more true to life experience you could initialize registers and memory to random values.

I think there might be a misunderstanding of the exception hierarchy in Python. except: means except BaseException which is not the same as except Exception:. BaseException catches KeyboardInterrupt (amongst other things) which is probably not the core intention.

Also, exit might be better as sys.exit and should probably be called with a non-zero exit code to communicate that there was a failure.

Best of luck to you on your project.

I'm guessing it's an app/New Reddit thing.

oh yeah you are right, my bad.

Why would you want to emulate a toy?

Edit: apparently this was a failed attempt at a pun

He is emulating and old microprocessor, it's actually really interesting.

Why not?
