Hi there,
today I found a HP35 with Charger on a fleamarket. Got it for 2.5 Euros (appr. 2.5$).
And I did'n look into the battery compartment before I paid for the calculator.
The calc has the Ser.No 1302S 75403 and the batterie are numbered 1420-0272. I think this means that both, the calculator and the batteries are about 30 years old.
They looked this way, a huge amount of crystals from the electrolytic and green and blue debris from the junction of electrolytic and copper...
The liquid managed to reach the supply-unit's plug in the calculator.
Testing with a regulated power supply, the calculator doesn't work :-(
I didn't peel off the back label yet, are there any experiences that the calculator can be get back to life?
