Wire list for the RKV11-D Qbus RK05 controller backplane anywhere?

Yeah, info does seem to be scarce.  Not even in my LEVAX fiche set.

But maybe decipherable?  Since three of cards are the same (per the
Wiki), those interconnections would presumably be the same as the
RK11-D.  That fourth card (M7268) is apparently a connector card for the
Q-Bus and drive bus.  No idea if it has additional logic on it or not.

An easier route might be to throw an FPGA on a dual height Q-Bus card
and reproduce the thing.
