>(Hancock) stated that it will run on all current mac models (ie. Power PC 603 and 604 chips)<
>However when pushed to support on the older 601 chips she could not guarantee this. Apple is still continuing to sell the 601 series at discounted prices.<
Hancock said that the new OS would be compatible with "units currently shipping" -- the only 601 unit being the 7200/120 -- which has a PCI architecture.
The older 601 "NuBus" machines, (6100, 7100, 8100) which debuted in 1994, were based on a *much* older 680xx design and *may* be orphaned.
BTW, the same backward compatibility limitations are true of the BeOS. The NuBus units, as well as the recently discontinued 190 and 5300 Powerbooks (due to the uniqueness of their construction), are not/will not be supported.
IMO, since early versions of NeXT ran on 68030 machines, I think there will be some form of backward compatibility.
In any case, I run a 6100/40/250/CD. Nice machine. 7.5.3 suits me fine. I'm not losing any sleep over the new OS.
