There was a Univerter and Qniverter (sp) which were used to
translate from unibus to qbus.Very useful boards and used one
to translate from vax730, vms 4.3 to a qbus expansion box, so
I could use an RQDX3 and RD53 as vms boot. Just set up the
dipswitches and it works automagically at power on.

May have docs somewhere, but not sure where...
