eBay Charging Cable

Thanks!

I actually have one of his cables (without the circuit) and it works great, but still I managed to burn a HP67.
I don't blame the cable, my problem was probably bad connection between the battery and the calculator.
Since then I don't really dare to charge or use a cable connected to them, but try to charge them externally, or keep the calculator off while charging.

(The 67 is up and running again after updating the main circuit board Smile)

Best regards,
Thomas
