Well, lots of things.
## Better code organization
I really had no idea what I was doing when I started this. So, like all code, it's going to need some improvements along the way to make it more organized and more maintainable.
## Improvements
* Keep track of input source lines and add comments in output to show where lines came from, for learning / debugging purposes
* Better / more efficient translation
* Support for 16bit math? Maybe? We need to at least be able to do 16bit pointer math
* Consider supporting the "Sweet 16" virtual 16bit CPU that Woz designed?
