I might be interested if no one else wants this.
You'll need a backplane too - and that's non-trivial. (I'm in the process of
producing one for a KE11-A.) The RK611 is a 9-slot (although several slots
are just SPC, and can be ignored).
Hence the plaint on my 'PDP-11 Models' page:

"DO NOT just keep the boards, and discard the box, bulkhead panels, cables,
etc. Everyone does that, as a result of which we are now over-supplied with
boards - but the cables, boxes etc are now rare (un-obtainium in some cases
..) These are all now worth a lot more than the cards are!"

Thanks Noel: The boards are not RK611 controller boards, they seem to go
in the drives themselves, maybe.
m7706, m7906, m7908,m7907
I don't remember RK07's much, they were quickly replaced by RL02's in
the world I lived in. Kind of odd little ducks.
I'm just trying to get rid of junk, and they're taking up space. I had
an RK611 in a Plessy expansion box but I think I sold that with my
11/34+2 RM02's awhile ago.

I agree. Fortunately, the few things that I have disassembled (which
include a couple of RK06's) I did indeed keep just about everything
except the case.
Coincidentally, I *do* have an RK611 backplane and cards. I'd be
willing to part with the backplane, but want to keep the boards as spares.

Noel,
I can I hope get the backplane and complete 11/44 that goes with it, plus
the RK06 or RK07 (I forget which). If you or anyone is really interested I
can try to track this one down. I have been trying to get through to the
owner, he has not returned my calls, but he's a nice guy and I hope to get
the remains of his DEC stuff asap. I was not super enthusiastic about
getting a RK06/7 drive for space reasons. Contact me privately if anyone
is interested.
I also reached out a guy that has a few complete 8i systems, trying to get
those too.
