Hey does anyone know offhand what the commands are fot the debugger that's
called up when you hit the interrupt switch on the side of the machine.
I figured out some from the MacsBug command listing.
(e.g. DM dump memory
	SM change memory
	G Execute at adress
	Dx,Ax,SR Display register x value
)
	Are there any other commadsd or is this all?
	Also where is the debugger stored? in ROM or in system software?
	And how can I substitue my own program in the interrupt service
routine (e.g. get my own routines to run when interrupt is pressed?)

Any reply would be appreciated...
