RE: HP97: Who was the killer (resistor or transistor)?
I have seen and repaired this type combo heaps of times, but usually in power supplies, mostly where someone has put incorrect power etc, or component failure.
However I would have thought just using the units batteries would not have caused that catastrophic result. ( I am not an expert in repairing calculators )
Thinking mechanical intervention would be unlikely, it is quite puzzling,
hope you get to the bottom of it.
Is the 97 a new acquisition, or did it happen while you owned it ??

Good luck with it

Geoff,
I bet that Gundig sounds good, terrible to work on, but a marvel of 60's German engineering
