HP65 and HP67/97 factory cards


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


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.
