Hi there,
Do HP-41 magnetic cards fit to HP-65 card reader?
Thanks.

Yes, magnetic cards for the 65, 67, 97, and HP-41 card reader are all interchangeable.

With the exception that the original HP-65 cards are setup for one-side use only, as far as labeling and corner-cut write protection go.

Blank cards, yes. Recorded cards, no. The recording formats used by the 65 and 41 are different.

Thanks!
