RE: HP 67: charging of battery pack
Thanks for sharing this information. It changed indeed my view, I didn't know, that the card reader electronics is connected to the constant current source of the charger.

I apologize and agree, that it is not safe to run the HP-67 without batteries. And it is also not safe to run it with batteries, because you could have placed them wrong inside.

My conclusion: The only safe way is to run it without batteries and without charger. Smile
