[A83] Re: Memory mapping
I've never tried it, so I can't say for certain, but it should. Keep in mind
you'd have to follow some rules for apps since you're in the 4000-7FFFh
area. Like embedding _puts and _vputs in your program, since those routines'
ROM pages are swapped into that space when they're bcalled.
