@ leolePPC,
I am in Brussels
Since you're there, maybe you can find it at a shop closer to you, like in the U.K. Try Power Computing - here is there
LINK. On their website, go to the Amiga section. Then do a search for "PCMCIA" without the quotes and it will show three results.
1) PCMCIA 90 degree adapter for use in your tower.
2) Power-LAN PCMCIA Network card
3) PCMCIA hardware reset fix board.
They will be able to sell you all the pieces.
Keep in mind that there are more U.K. shops available than just Power Computing. Maybe you can find one even closer than them.
