Wow, the big innovation here is that it's self hosted on a system with no disk. I don't think there's anything like it on the system - it's really an impressive feat.
FORTH on the 6502 has been done a few times before. There's a fellow named Garth Wilson who is sorta the self-proclaimed 6502 FORTH guru. He has a website here if you wanna learn more: http://wilsonminesco.com/stacks/
I actually wrote my own FORTH for the system before. My language wasn't very usable, but what impressed me the most was how quickly I could put it together. In just an hour and 100 lines of code, I had a fully featured compiler for a turing-complete language. You can't do that for many languages but FORTH!
