HP41/67 cards... - JasonG - 02-25-2004

Hi all,

I have a card reader for my hp41 (hurrah!) but I only have a few cards. Now, I could seek out some more cards on ebay but I feel the need to make some for myself. So, now I'm seeking a source of suitable (sheet or tape) magnetic material...anyone got any ideas or links?

I've seem some reports of people making their own cards. You need something like magnetic audio tape and a very thin plastic or cardboard backing. Spray auto trim adhesive can be used to fuse the two.

Then you just pray the thing doesn't delaminate in your card reader!

Working on these old calcs can be fun, but making your own mag cards seems a waste of time when you can buy packs of 80 brand new cards on eBay for six bucks:
