RE: HP-97 repair questions (a lot of)
First rule: do NOT EVER try to run these from the charger. Either ensure a good charged battery pack is present is solder a decent regulated power supply to the appropriate points on the PCB.
If you happen to have a spare board with a working CPU, I'd be interested. I've got a poor 97 with a toasted processor Pauli |
