But they dont make €20 16-bit PCMCIA USB cards. I am 90% sure they dont make them at all.
How much they would cost I can only guess, but like I said before, if they were really made,I think it will be a lot cheaper than the subway. *Edit: Such a card would be pretty much useless for todays Laptop market and if some shop still sells them, it would surprise me if the price would be in the same league as the subway.*
Anyway I doubt the existence of such a card also (see my first reply to the OP in this thread).
I want to make clear that I like my subway card very much, and I recommend it to anyone who wants an USB solution for his Amiga.
I just think a PCMCIA solution would be nice also.
