I strongly doubt there is any interest in them, I have also seen those ridiculous prices - unless as a collector's item practically they are worth nothing. Just about every surveying instrument today has on-board software covering everything these cards do and heaps more. If not for nostalgic reasons I'd have sold my pristine last series HP48GX with 2 Klotz RAM cards, cables and the printer (still with the 2 original boxes thermo paper).

I guarantee it will sell if you start @ $0.99

Well, I was able to get $50 for the card on TAS. $80-50=$30. Not bad for a pristine 48GX methinks!
