Yeah, there are 4 areas that work just like the user interrupt. One is the
interrupt, one is called when the calc turns on, one is called when the
calc turns off, and the other (I'm pretty sure) is triggered by the link
port somehow. At least the code that it's called from has lots of
reads/writes from the link port. Anyway, I think I've got the addresses of
the user routine areas on my web site...
