That's what is documented in Micronote #5. There is a comment in the

Yes, it can, and it works well. I ran RSX-11M from RK05s on my 11/73 system.
I even managed to find the article I wrote, on a 1986 backup of an RSX-11
disk, now loaded on SIMH on my Alpha/VMS system. I have already sent a
copy of the RUNOFF file (and resulting text file) to Dave McGuire, who
tracked me down, and will do so for anyone else who would like it.
I also have the RKV11-D manual and print set, but they are buried in one of
the many boxes in my shop, so it might take a while to find them. If you
need them, let me know and I'll dig them out and scan them.

That
fourth card (M7268) is apparently a connector card for the Q-Bus
and drive bus.
Yes, but actually there are 6 cards: the M7269 is a dual card which goes
into the QBUS backplane, and the M993-YA which goes into the first RK05,
to convert from the two flat cables which come from the M7268.

Also, it is only 18 bits.
Actually, only 16-bit DMA addresses, I'm pretty sure.
