This is awesome.

"You can scroll through memory as well" --> Would be nice to have a scroll-bar because I missed this at first and wondered why there were only 6 bytes of memory. (Would also be nice to see a bit more of the memory at once, although then the instructions might be easy to miss. Maybe a "show more memory" check-box?)

Would also definitely be nice to reset / modify the instruction pointer.

And of course the ability to save/load the CPU state (eg. simple copy/paste to the clipboard.)

Next steps would be to teach about basic I/O, since that's a fundamental part of any computer. (Start with some simulated LEDs/toggle switches that map directly to a special address space?)



A button to execute a single instruction would also be nice.
