That's the real trick. Though I suppose we could try to clone INTBASIC instead. Smaller and simpler.
The rest of the ROM...I implemented a high-level emulation of a lot of it that's far from complete (PR# and IN# are broken, monitor is incomplete, line input and some other smaller stuff is braindead) but it could be a starting point.
