I'm trying to keep this down to minimum bandwidth...

For the Following disks here's what I know about controllers...

Control Data 9762
Try Emulex and Dilog.

DEC RK07
There's no DEC Qbus controller.  Qbus to Unibus adapters will let you run this 
but it's unwieldy.  A number of controllers emulate these with 9762's.

DEC RL05 (I think)
No such drive. If you mean RK05, the controller you want is an RKV11.

Unfortunatly, this has only 16 bit addressing. 

Memory management doesn't work with the beast because there's only 16 bits
in the address register.  Support is in the software and a hardware hacker
can bus the stuff to the 2 bits that are not used in the register if you're good
and have prints.

A friend made the mods to one I had on an 11/23 that used to be an 11/03.
