That edge connector may be to connect all the keyboard tracks together for gold electroplating.

That must be some kind of early LSI chip! Really neat looking display! Hope you get it working, good luck!

I recently purchased a pocket panaplex calculator but unfortunately the batteries leaked and ruined the board but I'm hoping the display is still salvageable. Nice video as always 👍🏻

My first calculator was the TI-30 (the late 70's). The auto power off function would have been handy - If you forgot to turn it off, next time it was out of juice (a 9 volt battery).

I still have my Texas Instruments Datamath Calculator and it still works. I don't keep batteries installed.

I have a few Datamath, they still work too, while the build quality was not terribly impressive on those imo.

Display is filled with Neon (orange glow), not xenon (blue glow)

Essayez-vous de faire fonctionner à nouveau la calculatrice ? Je serais intéressé de voir à quoi cela ressemble sous le tapis de clavier noir. Je viens de le nettoyer entièrement et de le restaurer en grande partie. L'extérieur de la vitre du filtre d'affichage doit encore être poli ; il y a quelques rayures sérieuses. Cependant, après nettoyage, le clavier ne fonctionne plus. 😟

Bonjour Msylvain, J'ai franchi le pas et j'ai retiré très soigneusement le tapis en caoutchouc noir. En dessous se trouvent deux films Mylar superposés avec des contacts et des pistes conductrices correspondantes. L'alcool s'est glissé entre ces films et ne s'est pas évaporé. J'ai très soigneusement soulevé un peu la feuille supérieure et utilisé un petit sèche-cheveux pour évaporer le reste de l'alcool. Maintenant, le clavier fonctionne à nouveau. Ce qui ne fonctionne pas encore de manière satisfaisante, c'est la troisième position sur l'écran. Cela scintille. Je dois voir s'il y a des problèmes avec le pilote d'anode responsable.

w77102 What is it and what does it do?

My guess is a transformer to make the high voltage for the display. The other Sanyo black part is strange too, maybe a thick film ceramic resistor or some hybrid module.
