Testing Power Supplies! Re: Norsk Data Nord-10/S restoration

...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.) /~\ The ASCII der Mouse \ / Ribbon Campaign X Against HTML mouse(a)rodents.montreal.qc.ca / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
