RE: Classic (HP-67) charger / battery problem
Thanks for the responses Tony and Andi. I rebuilt a battery pack with fresh 1000mAH NiCd cells, and I left it charging over night. This new battery has charged enough to run the calculator on the battery alone, but the low voltage led is on.

Sounds like it's not or not just the battery, so I'll try another charger.

Tony do you know the pinouts for the supply vs charge on the charger plug ? I'm trying to get a good 65 and 67 to test the teenix boards you sent me :-)

Cheers,
John
