For anyone looking to buy a second hand PCMCIA card who isn't sure which ones are compatible, GMB has put together a list here -
http://www.g-mb.de/pcmcia_e.htmlI use a 3Com Etherlink III card with my A1200 with this driver -
http://aminet.net/package/driver/net/3c589And I use a Digital PC-LAN card with the cnet.device on the A600.
Good luck to everyone trying to get their A1200s online, it's heaps of fun once you've got it all up and running, especially if you have a 030 or faster, although that doesn't stop me from going online from my 000 A600 and my 020 CD32

Make sure you download Dynamite so we can all play an online game of Bomberman against each other some time!
