HP67 black cable broken

Yes! Under a magnifier you should see part of the remaining black wire in the centre. So vacuum up the solder with a de solder bulb or braid.

Then retin and solder when ready.

I actually de solder these prior to restoration so that I can clean the keyboard separately from the framework housing.

Cheers, Geoff

Another trick, if the solder points at the receptacle end need new wiring, plug the charger/wall wart into the calc but not the wall! This will hold the pins in place when you heat the solder.
