The calculator is in good cosmetic condition, but has problems:
Some keys are a little sticky, so it has to be cleaned. I did it once after removing the old batteries (no corrosion) and the situation has improved. Still, this has to be investigated and hopefully solved by another cleaning run.
A small metal plate is missing from the power connector, so the calculator is always in charging mode. I bridged two contacts reversibly.
The calculator came with a car/plane power adapter (12V). Removed the connector and attached a regulated 12V PSU (230V).
I exchanged the batteries, they keep charge now since a couple of month.
I have bought this calculator from eBay several years ago, but think it should find a better home. A pilot would be nice, a known member from this forum is a must.
Sells for best offer (money or an HP calculator).
I'll take fotos if there is a serious offer. I can even open the calculator again if needed.
