Yes, I do actually. I have tried the card in both 48SX calculators, and it does not work in either. I also have another equation solve card, and that works in both calculators, so my deduction was a bad card. I'm just perplexed why it would suddenly die.

I don't know how viable this is, but could you disassemble the case of those cards and see if there's finally a dry joint that's turned up? This of course assumes that such a procedure is (1) easy to do, and (2) easy to clip back together. If not, then I'm not sure what else to suggest.
