	will it be dependent just on the WinCE version; or it dependent even
on the ROM version? (so there will need to be a layout for the z50 different
from the Phillips <insert name here> different from the NEC <whatever>?)
	is the address that it calls, completely hard-wired in? is it
something sensible (like the last addressible piece of memory); or something
that needs to be changed every time you put a new wince ROM in? what
actually decides the address? is it on the ROM board itself, or some other
chip? 
	any hope of hardware-hacking it?
