Microprocessor is currently a class but makes no effort to protect its internal state when accessed from other threads. We should explore converting this to the new actor model. This will likely affect speed but this could be an acceptable trade-off

Microprocessor doesn't currently care about cycle accuracy so certain timing schemes that rely on this won't work with this simulation. Many C implementations already have this so perhaps we can look at those and add that to this implementation.

It would be nice to abstract Microprocessor to a protocol so we can have multiple 6502 implementations or even other 8-bit cpu implementations: 6800 or Z80 come to mind.

we are spending a ton of time just doing opcode comparisons. the opcode layout though is pre-known, so the multitude of Set<UInt8>s that we have should all be converted to a pre laid out (and possibly unsafe because we use every single number in UInt8) Array. then we can see what other speed improvements are possible.
