HP65 and HP67/97 factory cards Message #1 Posted by Paul O'Hare on 13 Jan 2005, 3:34 a.m. Hello all, apologies for posting such a simple question but are hp65 factory written magnetic cards (as found in the hp65Pacs)compatible with hp67/97 calculators? Cheers Paul

Re: HP65 and HP67/97 factory cards Message #2 Posted by Achim on 13 Jan 2005, 5:52 a.m., in response to message #1 by Paul O'Hare The cards are physically identical but the opcodes of the HP-65 are different from the HP-67/97. So it makes no sense to read cards from the other calc. If you try to do so, you either get an error or unpredictable results.
