Correct, NetBSD/vax in its current state will not run on any KA45.

Not to say that anyone here has any idea of how easy or difficult it would
be to get NetBSD/vax ported to it... which I kind of think is why Ragge
may have been asking about the differences.  ;-)

Outside of the CPU being different, there's also the matter of what type
of serial, SCSI, and ethernet devices are present in that model of VAX.
And then how they're all strung together.  Where's Antonio?  He may know.
