I have contacted the vendor by email to order one of those cables for the 67 and the 97!

Again, thanks for the pointers!

The HP-97 has charger overvoltage protection, but it only works properly if the original charger is used (or one that has the same specs as the original). If you use a different charger with higher current capability, then you can risk overheating and damaging the protection circuit if something goes wrong.
