Unfortunately, aside from ethernet, we don't support any of the other devices
on NuBus...yet. I hear tell that Bill was working on serial for NuBus cards.
You know about floppy of course :) and I think Allen made mention of SCSI on
a NuBus card. Video could be done. I just need a take apart Jet video
(of course, without a Duo, I can't :)

Just treat it like a NuBus card. Granted, it's a NuBus card that does
a whole bunch of stuff, but it's still a NuBus card. You could probably get
ethernet going pretty easily. I would imagine it has SResources and whatnot
just like a card. You just need to be careful only to map the appropriate
address space for the chip you want rather than the whole slot.

For instance, an ethernet driver might probe the slot, see that's its a Duo
Dock II, map in the ethernet chip's space, and then let somebody else have
a turn. Then video comes along and maps in the frame buffer and
video controller, etc.

Hmm. Check out the power manager code.
