Hello,
I'm looking into buying a graphics calculator.
Having RPN hardwired into my brain from 24 years of using a 15C, it has to be a HP.
While searching for a 48G I found this
48GX on ebay

The cosmetic condition is very good, but unfortunately, the calculator does not work properly anymore. Some keys activate two functions at the same time, e.g. when you press '3', the divide operation is activated, too.

What do you think, can this be repaired? I hope this one will be not to expensive.
Another question: How does a 48G/G+/GX or 48S/SX compare to a TI-83 in terms of speed. Most of my pupils use a TI and I don't want them running circles around me and my HP when doing, say, a numerical integration.
Do you have any recommendations like Rom versions/serial #s to avoid? I'm mostly looking for a 48G. If the RAM turns out to be to small I'll try to turn it into a G+ (if I can find a chip).
A GX in good condition is expensive, a S/SX maybe to slow.
Thanks
Rainer
