And I opened the pack up, and you are 100% right! It's just a plastic shell containing 10 big C-size cells, 3.5 A.hr each, indeed from the time period it must be NiCd! Now if I can find similar cells I will be able to reconstruct the pack inside the same shell. It will even look like the original.

Ah thanks, this is what these are for, thermistors. They are supposed to monitor the temperature somewhere I suppose? Attached to the batteries? The power supplies? The computer won't start without these I understand? Sorry I am a bit of a newbee with HP 1000's. Have not tried to power mine quite

I've got some pins that appear to be the right size from when I was making battery packs (electric R/C) that I plan to solder to the resistor with a little bit of heat shrink on each leg to keep from starting fires or other exciting things from happening. A sorta kludge. I remember using these
