Well, I'm in love with Unibus systems... I have an 11/84 at home, and of
course, there is always Magica, which is an 11/70... :-)
(And then we have Knase, which is our 11/70 with 2.11BSD. Unfortunately,
both systems are powered off right now because of cooling problems. :-(

I don't think the DEUNA has that bug which riddles the DEQNA.
Also, the DEUNA/DELUA loads some microcode when I start using them, this
is running RSX. That microcode is located on the RSX system. Beats me what
it is for, or anything.
Worse (parhaps) is that the device driver for the DEUNA/DELUA don't work
with any Q-bus models, which means I don't have a driver for Q-bus
machines...

Anybody know anything more about this? I really don't care to dig around
the sources here, and also, I don't have the sources to all components.
