I have two Ariadne-II cards. Used to have them both installed in my A4000T when I was using that as a gateway machine for all the other computers on my network. Since have bought a LinkSys switch to put in between my cable modem and my computers. No longer needed both cards in that case, so I removed one of them and am just keeping it for a spare. The other that is still in my A4000T is quite a few years old and still working perfectly with Miami Deluxe.
