Ok, I give up, what the heck is this? QDA "Quad" processor. Ok, is it used
for clustering or something?

KFSQA - Q22 DSSI Controller, the drives hiding in the cabinet are two
RF71's. So it looks like 1.6GB about of disk space. Of course I have no
idea if the drives work or not, but it is beginning to look like it will
make sense to get one of the BA213's together as a "real" machine.
(Generally the machines at these auctions have been either intentionally
stripped of things like disk drives that might contain "valuable" data, or
they have been used as parts sources and so are not complete.

So here are some "skunk box" questions:

What type of backplane is this? Looks almost like it is Q/CD all the way
across.

There is an ethernet interface in one called a DESQA any good? Seems like a
follow on to the DEQNA as it has both 10B2 and AUI ports on it. The other
two chassis both had DELQA's in them.

Since my uVAX II is chomping along now as a uVAX III with the KA650 I think
I'll leave that as is. One of my other TK70 drives has the plate attached
so that answers that question, and by careful disassembly I can see that
the connectors are correct in terms of how I plugged them, so the only
question is if the fault was a board short or if the power connector is
non-standard. Anyone?
