Re: HP 97s charger Message #4 Posted by Thomas Okken on 28 Apr 2005, 6:11 p.m., in response to message #3 by Paul O'Hare
I used to own an HP-19C, which uses the same charger. The charger that came with mine had the plug with a notch between the two contacts, but the connector on the calculator side did not have a bar between the two male contacts...
From what I remember, the chargers with the notch had a somewhat lower output voltage. My guess is that the models that required the "notched" chargers could not deal with the higher voltage of the non-notched models. But I'm sure someone will prove me wrong. :-)
(Hmmm, on second thought, I might be confused between the 19C and the 82143A (printer for the 41C). Still, I seem to remember it has to do with the charger's output voltage -- 8V for the notched, 9V for the notch-less ones? I'd be careful trying to use a charger with a device that it wasn't meant for -- that notch is there for a reason.)
