I've recently been attempting to revive my 34c after many years in storage. I've acquired replacement battery packs from Digikey (they were great to deal with!)as recommended by Katie Wasserman's article in the museum (the part number has changed from p253-f021 to p229-f021, by the way). The calculator works as I remember, and passes the self test.
Which brings me to the charger. The original was lost or discarded inadvertently (though I recall a certain cat chewing through one power brick's cord, perhaps this one.) I found one in short order on ebay, anxiously waited for it to arrive, only to find that though it was the correct model 82087b, the adapter plug did not snap into the calculator snugly, and when jostled caused random segments to light up in the display. The calculator is fine, but makes me wonder about this adapter, as I never put the calculator to hard use and always remember the power plug snapping into place.
Does anyone have any experience or suggestions with revitalizing heavily used contacts as these may be? Does anyone have a picture of a connector in prime shape? To my untrained eye it almost looks like there might be a plastic insert missing on the back side of the connector that would provide additional tension on the contacts that would make for a good fit. There's no apparrent damage, but I can't be sure.
And as another alternative, I've pondered looking for another calculator in the Spice series in order to get my hands on a working adapter. The question here is which calculators shipped with the 82087b chargers? Just the "c" series calcs, or did the later "e" series as well?
My thanks to any and all that have any information on these questions. I appreciate your time. This web site really is a wonderful thing!!
