OK, posting version 1.0 - hopefully somebody finds it interesting. Everything I mentioned in the previous post is done. No hardware interrupts at this point, but there's no peripherals that would need one yet.
Get it here.
The docs need some work, but if you're the sort of person who's interested in this kind of thing, the architecture and brief instruction set are probably all you need. Maybe the peripherals. I've included a test assembly file that I think exercises the entire instruction set.
BTW, the files are hosted at cx.com, as an ex-coworker of mine works for them now, and it seems pretty cool.
