Reading old HP-65 program cards

[albertofenini]

That would be amazing !!!
We have restored quite a few HP65s
In our experience writing has been usually more tricky than reading
Of all of our units all can read the majority of cards whether it was a standard pac, and believe me we mixed them a lot, or an application pac or even a previous owner card
Few units have given us a hard time with the WA and WB signals but replacing the amplifiers has mostly been a good fix

Reading, and copying , those cards would be close to find the holy grail of the HP65

Good luck with that and let us know !!!!
Take care
