You're fine, as long as your 11/73 has less than 248
kbytes in it.
The RLV11 won't DMA any higher than 18-bits; if you've got 256kbytes
or more of RAM, you want a RLV21. > The 11/73 has an RQDX2 and one RX02 8"...

What backplane are you using? Most BA-11 backplanes are ABCD with
9 slots including a terminator board which MUST be the last slot you use
and is usually the last physical slot since bus grants are not a problem
with regard to termination. The ABCD slots are quad width and accept
dual boards as well, but the other half MUST stay empty.
The RX02 requires a dual M8029 (I think it is called an RXV12) with
a 40 pin cable.
The RQDX2 allows RD51, RD52, RD53. It is a quad board (a -YB).
Most will not accept an RD52 from an RQDX1 without re-format.
If your backplane is stuffed, what else do you have?
Sincerely yours,
