Rather, I think.  The MVs preceded the 88k-based AViiONs and were
proprietary.  There may be significant documentation out there for
them, but their speed will not justify their power consumption by
any stretch of the imagination.  In short, it might be neat, but probably
not worth the effort.

If I recall correctly, they have a Nova-II inside of them as part
of the bootstrap.  Again, IIRC, DG/UX used a different microcode
than the DG-proprietary AOS/VS -- the microcode was loaded by the
Nova and then the OS was bootstrapped by the microcode.

DG/UX 2.10 or 2.11 running on the MV4000 was my first exposure to
Unix (in 1986).  I don't remember a whole lot about them, though...
