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
