...if you have Tony Duell's workshop and tools available.

I, for example, have few suitable dummy loads at hand. I have a load
resistor which came form an old Sun (4 ohms), though I'm not sure
whether it's between 5V and ground or 12V and ground - it I suspect the
latter, since it looks more like 36W than 6?W. (It could even be
between 5V and 12V from what I can tell, though that would be Weird.)

I actually do not even have a reliable voltmeter, much less the
properly working oscilloscope I'd want to check things like ripple.

Of course, I also generally work with machines that, while classic
according to our definition, are not nearly as priceless as, say, a
Norsk Data 10/S; they tend to be more like SPARCstation IPXen. (Thus,
both less likely to have a fried PSU and less damage done if so.)
