Then we changed card reader with a HP67 style where we have changed all the capacitors
However the bakelite of this card reader (the part where the head is fixed) is very ruined
and we have trouble in inserting a blank card or a card from an HP65 standard pac.
We think that these three cards have probably different thickness and only the card from
the HP67 standard pac goes thru.
The card reader however produces a good RA and RB signal and some times read succesfully
the card.

Later we will try to combine the two card readers in a single working one,
will post the resutls here !

take care !
