Having just aquired one of each (DEFZA & DEFTA), I not two days ago looked
around a little for that same info.  There are some google hits on port-pmax
that indicated ~40Mb/s is all you'll see with a DEFTA, being as it's an
older card.  I popped the DEFTA into the M800, and left the DEFZA in the
M300X.  I've got NetBSD on the M800, and I'll be putting OpenVMS back on the
M300X, so it can live peacefully in the VAXcluster.  [OT: OpenVMS _does_
support the DEFZA, doesn't it?]

Did you manage to get the FDDI card working with IRIX?  What kind of switch
are you using?  I want to put a 8-16 port switch w/ FDDI uplink in my rack,
to reduce the number of cables coming out of it to one power and one fiber.
That should make it a little easier to move around!
