There's already a lot of code in tree to support the 601, but I think that
people who know better can update all of us as to what remains to be done.
I also have a number of 7200 style machines which would get some use when
NetBSD runs on the 601.
I also have a 601 on a CPU card from a 7500 (I guess) for any developer
which wants to work on 601 support, but doesn't want an additional

Since the first gen PowerMacs were much more like Quadras than like Open
Firmware machines, it'd be a lot less work to use stuff from mac68k, like
the booter, the hardware driver and NuBus code, and so on. A native booter
for mac68k was never a high priority, so I can see the same being true for
first gen PowerMac.
Didn't someone play around with making the booter load a kernel on PPC and
having it start that kernel?
It's bee a while; maybe we should go look at the mail archives...
