It won't make much difference.  Personally, I put it in front, but 
that's largely force of habit, born out of the need to place any RQDX1 
as the last item on the bus because of the way it (doesn't) pass grants.

In general, the recommended order on microPDP-11s is:
  Ethernet and/or synchronous comms, eg DEQNA, DPV11, DRV11
  printers, eg LPV11
  other serial comms, eg DLV11, DZV11, DHV11
  tapes, eg TK50, TK70
  disks, eg RLV11
