I need to test an HP82104A card-reader (just received) with my HP41CV, but have no cards. I do have a heap of the long cards for the HP75, so wondered if those would do, cut to length. They may be too narrow.

Can anyone give me reasonably accurate dimensions for the original HP41 cards?

Or perhaps does anyone in the UK/EU have a few spare cards I could buy to try?

thanks

I have a lot of original HP41 magnetic cards, with holder if you want. Can ship as a letter from The Netherlands

Don't cut up 75/71 cards! They're much harder to find. I'm sure someone would be willing to trade you 41/67/65 cards for them.

OK I’ll put away the scissors! Looks like Meindert is kindly helping me out.

My card reader is not working and I have a bunch of blank cards.
