That's the impression I was under. While I don't even know what a BAT
one need know PPC assembly to add 601 support (to NetBSD)?

If Linux can do it, why can't we? :P I don't know much about the PDS
but I would think you would need NuBus and/or PDS support before any of
upgrades work. However, it would be rather interesting if we could get
NetBSD i386 to
boot on the DOS card that comes with the 6100/60 PC models :)

Are you refering to getting the machine to a state where a serial
console will work
or including using the video hardware (How does one do this on our current
setup as we
have no console video drivers) We don't need NuBus to attach the built in
video hardware to?
I'm not entirely sure how all that works.
