Anyone using RK06/07 drives?

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.
