True. But part of my point is that to the users, they (NuBus and PCI
PowerMacs) are the same class of machines, while I think most users
would consider hp300 and sun3 to be different machines. They run the same
MacOS, so where's the difference (speaking from a user's point of view).

And my point is it'll be a marketing mess. :-)

Also, if we want to use the Apple booters (which would be nice), we have
to be able to quiesce (sp?) OF (or run with it quiesced). To be able to
run w/o OF callbacks is most of the same problem as running on NuBus
boxes. So if we solve it for one, we solve it for the other. :-)

I do realize we also have to support the 601, and pull nubus code over.
But no OF is the biggest problem.

Actually they dropped the OF 1.0.5 PCI machines too. They only support
machines Apple shipped with a G3 or G4.

Take care,
