HP-65 card reader - purpose of WE pin

[albertofenini]

Hi Tony
thank you very much for your support, we haven't been able to post pictures will do it soon,
however, in HP97 is easier because the screws that tighten or loosen the switches are accessible
with the card reader in place, while in the HP65 you need to dismantle everything, tune the screws,
reassemble the unit and check if it is ok, a little tricky but can be done.
We are now facing a new challenge with a unit (the last one by the way) that as a WB channel noisy
and does not record cards.
Any idea is welcome, take care !
