Wow, I would be amazed if I had that much stuff to run on RT-11. I've got
to get the 11/34 set up now in the rack with the BA23 extender box. So it
will now have:
         Kennedy 9610 (compact 9trk)
         PDP 11/34a
         BA23 expansion chassis
         RLO2 (on the bottom)

All in a low boy rack if it will fit. (it should, I think that is only 25
out of 28 "U" for that rack.
