I knew that would get a rise out of you :) Yes, I can do some tests on
it. Swapping the supply is super easy (two thumbscrews on the target and
donor units and it's free) and that would at least tell me right away
where to look. Then I could focus on either the bad power supply or look
elsewhere for the problem.

Oh, come now, Tony. You've expressed a desire to have one in the past to
examine. If you ever make it over to the States then I'll give you one of
my extras.
The fact that it is very easy to disassemble should not be a mark against
it. It is, after all, one of the first mass-marketed GUI computers. The
design is rather elegant. Everything can be taken apart with the thumb
and forefinger. It's very easy to work on.
