Rebuild of the keyboard

Hi everyone !!
Another small step forward

We have completely dismantled the other spare unit keyboard and
cleaned every single dome
First tests show that all the keys are now functional
We are using the wires that usually come with a breadboard
in order to replace the original cable connector

Next steps are now to glue back the facelift using double sided tape
And reconnecting the card reader

The card reader is mechanically working
We have rebuilt the gummy wheel and a card
is transported with constant speed across the card reader

Electronically tests still to be done

AAA batteries springs are on the way and will be used to replace the broken battery contacts
