Could be any number of things...  The cable is probably
a bus connector and the cabinet in the other rack is
an expansion cabinet.  What you are looking at could
be a PDP 11/05 (I used to have one), although since you
didn't mention there being a row of switches across the
front, probably not.  

There are so many different possibilities.  If you could
describe the front of the boxes that are in the rack it
would be very helpful.  The PDP 11 possibilities and fit
in a 5 1/4" (half box) would be a pdp 11/05 (with a 
row of white keys (16 of them), a pdp 11/23 (which is 
mostly white with 3 white keys in a small inset area)
and others that might have a rotary switch or perhaps
a telephone-like keypad).  Otherwise I would wonder if
it is even a DEC machine...  If it has an orange lighted
rocker switch it might be any number of later Q-BUS 
machines....  (and probably so if this has a SCSI device).
