VAX9000 unearthed

I thought XMI was only supposed to be a CPU/memory bus, with IO being 
done by multiple VaxBI busses. That's what we had on the 6000 at the 
computer Society: 2 CPUs, memory, and two VaxBi with a SCSI disk 
controller on each.

I think it also had serial connections via terminal servers because the 
ceiling in the computer room collapsed shortly after I started working 
there from all the RS232 cables piled up there. Landed right on the 
SparcStation 20 and "crashed" our WAIS/Gopher server.
