True.

Yes, and much cleaner. :-)

I had a chat w/ Jason after sending that, and that's about what he said.
He also suggested making it soemthing like:

bandit* at mainbus?
bart*   at mainbus?
mpc*    at mainbus?

pci*    at bandit? bus ?
pci*    at mpc?

nubus*  at bart?

(bart was the name of the nubus controller on the 6100/7100/8100
machines).

Take care,
