; Entry:	(Status indicator routines)
;
; Function:	
;	When execution of 68000 power-on begins, ShowInProgress (which could turn on all LEDs)
;	is called, indicating that the test is in progress.  If primary init crashes
;	it will then be evident that testing did not complete.  If any tests fail,
;	the routine ShowFail is called (perhaps to leave on a red LED), and if all 
;	self-tests pass, the routine ShowPass is called (perhaps to leave on a red LED). 
;	ShowOff is called to turn off all indicator status.
;
;	Note that these routines differ from the 4 status indicator routines in
;	ApplPrimaryInit.a in that they are not performed accross NuBus, but by the
;	cards 68000.
