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.

Not really. I
just need to swap power supplies to see if that is in fact
I will prentend I didn't read that!.... Can't you at least use a
voltmeter to see if the PSU is giving out any voltages? I seem to
remember there's some issue with a 'soft' power switch on the Lisa
controlled by a microcontroller (COP 400?) on one of the boards. Could
this be the problem? The Lisa is
the ultimate module swapping computer.
I knew there was another reason why I didn't want one...
