How about a view of the keyboard side.

Geoff:
Thank you for writing in capital letters.

Here is an image of the original and the new keyboard. I made the contact areas identical and manufactured it with chemical gold coating. There is no necessity to use the original keyboard PCB. This would be rather difficult anyway, because the separation of the ceramic layers is not easy.



Following images show different views of the prototype board before assembly.



I'm very glad to have a prototype now to get all functions running. One of the challenges is the running stopwatch during sleep mode and the perfect power management.
