*chuckles*  It's used for mapping large chunks of physical memory to
virtual memory locations, and the 601 does that stuff a bit differently.
Worse, the NuBus (PDM, anyway) machines do it slightly differently from
the PCI 601 machines, IIRC.

No, not positive.  I thought its stock card was a 601... I know the 7500's
was a 601, and the 7200 is a non-upgradable 601, AFAIK.  I've only seen a
7300 once, so....
