That's not the point!!!!  What the previous poster (name unfortunately lost)
was trying to point out is that digging out the specific place in the ROMs
for all of the different MACs and ROM versions is pointless, frustrating,
and potentially dangerous.  If the cirumstances permit you to run the
finder, this will work on every Macintosh:

	SM 0 A9F4
	G 0

This uses the jump table and allows the ExitToShell routine to be relocated,
ala Mac ROM style!

Cheers!
