It doesn't generate an NMI in any case.  I think that the ROMs or
the egret do interpret a 3-finger salute on the IIsi and other machines
(CMD-option-Power to reboot and something else to enter macsbug?).

On II-type machines, the power key runs in a line to the power-supply
to kick the power on if it's off.  If the circuit is on, it does
nothing noticable (I think it puts a drain on the battery, but I'm
not sure).
