Hi Everyone, we fixed it !
As we said in our last post we have swapped the card reader bakelite and with this also
the magnetic head and the plate with the battery terminals.
We kept however the logic part of the card reader, where at the end we re-soldered the
original capacitor.
The replaced one was too big and didn't allow to close the case, we could have soldered
with cables but we gave a try to the old one and it was working fine.
We read many cards from the standard pac, both one sided and two sided and
we also recorded cards both one sided and two sided,
however, we were not able to read HP-65 standard pac cards.
Shouldn't this be possible for backward compatibility ?
Or was it between HP-41 and HP-67 ?
Never mind, in the next days we will try to repair the other HP-67 faulty CPU board
take care and thanks for all the support !!
