Boys be careful!,

If you plug a Nubus-card in an appropriate PowerPC, you will run into driver
problems. The driver installer checks for the processor and will take the wrong
driver that won't talk to the Nubus-card. If you plug a G3 to a FACScan, in
addition to the driver problem, hardware modifications to the FACScan interface
kit (in the 'Scan) have to be done. So, you will need, at least, the PCI card from
BD (or does anybody knows a clone?).
So, never change a running system. (The Quadra is still a nice Mac)
