That is correct. Only the model numbers 3CRWE62092
B or 3CRSHPW196 cards will work on the Jornada. The A version you have has a different chipset and won't work.
I frequently used the B version of the card on my Jornada 728 long ago
(with the Alpaxo drivers/utility of course
). I also sold a number of them on eBay and never had any complaints. It looks like you could get one inexpensively
in this eBay auction.
