HP-65 card reader - purpose of WE pin

[albertofenini]

Guys we fixed it !
We tested the switches and the WPS switch was not closing at all ...
We had to work a little has we raised it too much and then it was always closed
However we got the right position and now it read and write cards like new
To be honest we think that the clutch should also be reinforced so will take care of that sooner or later
Will post some pictures tomorrow !!!
We want to thanks everyone for the technical and moral support and encouragement !!!
