	At least with Amiga-500 it is possible to just swap prosessors.
	Hardware compatibility is ok.

	Main problem is software which has some differencies:

		1) Exception stack frames are different

		2) Moving from CCR is made privileged instruction

	Point 1 is at least in Amiga handled is opsys, although
	some problems arise in some extra drive handling.

	Point 2 is totally upto programmer.
	Instruction may be avoided or emulated if needed
