I've just checked with both the KA675/KA680/KA690 System Maintenance Guide and
with the Addendum to the KA680 Technical Manual and both of them agree that the
KA675 (VAX 4000-400) is based on the NVAX chip (DC246).

Mariah was used in the VAX 6000-500, the MicroVAX 3100-80 and the VAXstation
4000-60 but that's about all.
