OT: VAX 4000/300 - test-drb@ccmp.vtda.org

...
 Hello.  This 4000/300 has been dominating my computer
room for a while, 
and I love how it looks, but it'd be great if it worked.

The boot-diagnostic LED on the inside panel is stuck at 'F'.  I don't have a
field service manual, so I don't know the exact meaning.  I've checked all 
of the boards inside to make sure they're snug inside, but no luck.  Nothing 
shows up on a terminal hooked up to the MMJ jack.  The drives seem to 
power up. 
This means that the DC OK signal on the backplane isn't being asserted.
If the Q-bus consists of more than one box chained together, this
typically means that at least one of the boxes' power supplies either
isn't working or has a sick DC OK signal.
