Error 0 and Error 4 without doing any key operations seems to be a defective ROM or processor. As you have a soldered version of this calculator, the usual contact problems of the solderless type cannot be the reason. I will build a repair kit for the HP-34C until november of this year. It is based on the Woodstock LP circuit but fits into the HP-34C case. A prototype is already running. This would allow you to repair your beloved calculator if only the display is still OK. Bernhard That's one small step for a man - one giant leap for mankind. |
