That's been my main point of research.  But not a lot of deeper info is on
that page.

The way my code is set up, what is loaded into C600-C6FF and D000-FFFF is a
patched Apple ][+ ROM - more specifically, patched to play nicer with the
/// (at least on MESS, the monitor just about doesn't work because of the
VIAs, and some commands do real weird things because they don't expect the
///'s hardware).

Basically, on MESS, I use Ctrl-Reset to start booting a disk.  It also seems
to put the system in lockdown.  I don't know what's behind that.  Partially
dasm'd the boot rom and don't really understand it, and that page only has
the barest minimum about how they work.   This is a bit of an issue because
I want to write a tool that swaps stuff out of the D000-FFFF area repeatedly
from an alternate code bank. (that *stuff* being the patched firmware and a
copy of ProDOS-8)
