No. The RK8E (and RKV11-D Qbus controller) uses a cable which consists of
2 40 way ribbon cables with BERG connectors on the controller end and a
PCB (with at least one chip on it) on the drive end.

The RK11-C and RK11-D (2 versions of the Unibus controller) use a flat
mylar cable with little PCBs (no componets) on each end.

It's not slots you need, since the RK11-D cards fit into specially wired
slots in their own backplane. It's space for that special backplane.

Aasumming your 11/34 is in a 10.5" mounting box, you have space in that
for either 3 4-slot backplanes or 1 9-slot and 1 4-slot backplae along
with the special 9-slot backplane that takes the CPU cards at the right
hand side. If you still have space in the CPU box, then you can put the
RK11-D there. If not, then you need an expansion box.
