Anyone with the customer diagnostics (and a uVAX II) can reformat it,

I bought a SCSI controllers (CMD CQD-240/TM) for mine, and I run a
single 1.2GB drive. They are quieter, and more reliable. This is
a fairly expensive solution... I paid $800 each for the SCSI controller
(refurbished, from a DEC reseller... Foolish me...), and $200 each for
the drives.
In one of your other EMails, you expressed an interest in VMS... You
can get a (free) license for hobbiest use for VMS from DECUS... You
have to buy the CDROM, and then figure out how to get it onto the
disk. Booting from a Linux system is apparently possible, though
I haven't tried it.

These are the breakout panels for two DHV11 (or is it DHU11) serial

You can probably find one on EBay for ~$10 (they aren't very popular).
The pinout is a bit strange:

Great! now all I have to do is solder.
The three position rotary switch controls the
power up mode
(arrow is normal, face is language inquiry, i dunno the other one)
Ok, so nothing bad would happen by choosing the wrong one. This
switch really was a big question mark for me.
The maximum amount of memory you can have in a
uVAX II is 16Mb, using
two 8Mb memory boards. Unless it is a VAXStation II/GPX in which case
the max is 12MB (or maybe 13MB)... You don't have the extra three cards
to make it a GPX system.
Apparently, there used to be other cards in here; there are four
small PC's fixed in the inside of the back panel, each holding
four DB25M connectors, but the ribbon cables coming out of them
are not connected to anything...
75 or so MB
MFM hard drive. Probably dead... They never were very
good.
hmm, everyone has expressed the same opinion about the drive.
Tony at least said that it was fixable, what he did not say
was whether he was the only one who could possibly fix them :-)
Thanks for all the info!
Welcome! try http://vaxarchive.org for more stuff... They seem to
be having trouble staying up though, so try at different times of
the day.
