DEC doesn't make anything for the Q-bus for this disk. Check out the
third-party companies; we had such a controller at my previous employer, but
that was a very long time ago and I have forgotten who makes it.

If there is a DEC controller for this, it will only support 18-bit addressing.
Depending on the O/S that you choose to run, and the type and amount of memory
you have, this may be a problem. I have no idea about third parties, but I'd
doubt it.

No such drive. If you mean RK05, the controller you want is an RKV11.
Unfortunatly, this has only 18-bit addressing, so it might not be good for you.
Again, I doubt that any third-party controllers would work.

If you mean RL01 or RL02, than you are in good shape. The RLV12 controller will
support them, and has 22-bit addressing. There is also the RLV11 varient; this
one is 18-bit only, and I'm not sure if it supports the RL02.
