The RK8E is a 3 board set that plugs into the Omnibus. There are a set
of cables that go from the RK8E to the drive. Taking an old BC11 cable
paddle and rigging it with connectors for the cables from the RK8E *may*
be the easiest path. The cables from the RK8E is two ribbon cables
(forget how many conductors right now). The drive terminator is nothing
more than a plain old M930 (Unibus terminator).
