One of the first PDA's from back around 1989, that makes it 30 years old now.

It's most likely your unit is no longer capable of working, as electronic devices do break, and nothing lasts forever. It certainly sounds like you've gotten your use out of the dinosaur that it is.

Time to get something modern and up to date.

ERR80 indicates a problem reading valid data from the EEPROM at power-on ("Protect area read error").

It is probably necessary to replace the EEPROM to fix this.
It is then necessary to re-set valid values for each address in the EEPROM by following the instructions in the link below:
You may need a repair center to do this for you if you are unable to do it yourself. A Sharp specialist should be familiar with this procedure.
You could try the re-set procedure first without replacing the EEPROM in case it's just a data loss.
