HP 75D power supply

[rprosperi]

The normal HP 82059B/D works for both the 97 and the 75C, as well as the 91, 92, nearly all the HP-IL peripherals, etc.

A good summary of the various models by country be found here, under "Topcat, Sting and Coconut Series chargers":

So, yes the 75C uses a 8-10VAC power supply, that webpage is simply wrong. Many people assume that all such wall-warts put out DC for electronic devices, and publish such assumptions as fact.

I'm not EE-nough to say if a special DC supply might work OK, but HP didn't supply one.
