HP65 vs HP67 card reader - Alberto Fenini - 04-17-2011
ciao a tutti,
I'm trying to repair the HP65 shown on the left of the picture,
it is working but the previous owner has ruined the head cabling.
Between my HP67s I have found the one pictured on the right,
which differently from the others has a card reader apparently identical.
What do you think ??
Can I take this HP67 card reader and use it on the HP65 ??
Or, on the other hand, does anyone has ever found a replacement for
the HP65 magnetic head ??
As usual, thanks for any suggestion, enjoy the weekend !!!
Alberto

Ciao Alberto,
IMHO, you can swap entirely the card reader assembly (head/motor/Reader PCB) among the calculators. The 67's sense-amplifier is compatible with the 65, I have changed this chip with success in one of mine.
For sure you can't make damage to the calculator's logic PCB.
About your second question,

take a look at this old post:

Let me know how the work proceeds,
take care.
