Oliver, don't forget to context-switch all ProDOS / Dos 3.3 global
state like zero page, $3xx page, text-screen holes, whatever else was
there. Also you'll have to deal with interrupts that may have been
running under ProDOS, and redirected I/O vectors. Maybe bunch of other
things.

Another thing that will require some hacking is to make possible
ProDOS to run out of AUX memory - it probably likes to play with the
soft-switches a lot.

Very interesting idea, though. Good luck!
