There's a Micronik A1200 tower in the club with that bussboard and a GoldenGate2 bridgeboard to activate the ISA slots and an ISA ethernet card connected. Only drivers I found for the GG2 card was Ethernet, IO, IDE and a special Soundcard... wish there was some graphic drivers also for it but havn't found any.
The PCI slot's I'm afraid are useless. Need a noneexisting bridgeboard for them to be active... I guess the best use you can get from them is one of these "PC on a PCI card" and thus having both a PC and an Amiga in the tower.
