    A friend of mine has a modified (read 500 in 2000 case..) Amiga 500
that is having a wierd problem.  And since I am his service agent (pizza,
once a year for full coverage ;), I thought I would shoot this out on the
net and see if anyone has any idea what could be causing it.

    Problem:
      After about ten minutes or so (sometimes it can be much longer, but
      it mostly lands on ten minutes) you can here a soft *click* and the
      screen goes blank.  At this point, the machine is locked up except for
      the sound chip! (ie, if there was a auto-repeat sound loaded, it keeps
      going).  All other function except reboot are disabled.

    configuration:
	A500 (1986) w/ 1084 monitor.
	a501 ram module
	Spirit inboard 1.5 meg board (fits in CPU chip socket - CPU plugs into
	    it)
	Cltd SCSI controller (new model, w/ autoboot)
	1.3 roms.

    Diagnosis thus far:
	I pulled the case and cleaned and reseated everything.  The machine
	ran for about 2 hours and then died.

	I pulled the Hard drive controller...
	   While playing a basketball game, it locked up again.
	   My friend then rebooted the machine w/out a disk and left it
	   on overnight - - - it did NOT lock up.

	   (ie, w/ the "insert workbench" thing up, it went ok...hmm,
	    and the monitor was turned off. I begin to wonder....)

    so, any ideas?
	(With any luck this guy will be buying a 3000 this spring and thus
	 we can retire this thing.... :)
