O.k I found the box. It´s a "Cherry1394". The Model Number is 69121 (1394+USB2.0+ LAN Combo Card).
Crazy the german description at my 2nd Link above says "not for Beige G3" but that´s exactly where I use it without any problems. Is there anything about a beige G3 what can make PCI-Cards working in every PPC from the 7xxx to the latest G4, except Beige G3, ... ??
