    I must say, that in this day of 16-layer PC boards and sub-
millimetre land-spacing on chips, *that* was a tour-de-force
of visual sleuthing.  I'd have given up after 'scoping the
output of the fans!  Well done!

    In my defence, though, I was able to discern a failled surface-
mount capacitor by nose on the underside of a dead motherboard on
an SGI Indy once (although those days are likely long gone by).

    In short: ROCK! BLOODY! ON!

    That's awesome news, and thanks for sharing it.
