Although I did this some years ago to a FatMan, I think I can be very helpful
here, I'm quite an expert at this.  Simply connect the -15 volt supply output to
the +5 volt Vcc input.  It is most effective if you do this while the system is
powered up.  The lesser part of the skill came in handy fixing what I blew up.
