Texas TI-59: A tale in pictures

[jebem]

So I saw this Texas TI-59 for sale, complete with charger, hard case, french manual, Master Library Module ROM 1 complete with the full 25 program cards, a bunch of magnetic cards with some of them have blank clean labels and probably never used, and at last but not least, some cleaning cards, one of them still sealed.

The bad news is that the calculator was another victim of battery leaking and someone tried to repair it, having done an incomplete job on removing the electrolyte and have replaced the original NICd battery with one modern mobile NiMH cells soldered to the PCB.
And to add insult to the injury, the new battery is dead having two of the three cells in short circuit.
So when I opened this machine, I saw a total disaster in the keyboard domes, as the battery leaking had time to attack under the domes, and the calculator is doomed as it is.
I needed to find a keyboard donor, and a TI-58 is under his way to rescue.
