VAX 11/780 help needed.

So, I've got power run now, and am trying to get the machine up and 
running.  After I figured out what baud rate it wanted (and reset it 
down to 1200 baud from 1800 baud), I've been trying to figure out a 
problem...

So, when I connect a terminal to the console port, all I can get is an 
address: 173002, followed by an "@" (the ODT prompt).  Trying to examine 
the addresses using ODT fails.  So, it looks like the bootstrap PROMs 
are not accessible for some reason.  From what I see, it appears that 
they are actually contained on the CIB (Console Interface Board) in the 
KA780 CPU.

Can anyone verify this, or have any suggestions what I should check?  The 
power supply bricks all have their "POWER NORMAL" lighs on, and seemed 
to have a good 5V output from testing with a dummy load and DMM.

Any ideas?  I'm a bit stuck here.
