 Hmmmm, now this sounds ponentially very cool! 
According to the Field
Guide this is a "Dilog ST-506 emulation of four RL01/02".  Any one have
info on this, and will it work in a system that has actually RL02 drives
attached? It would make it a lot easier to get data on to the Hard Drive
if I can just copy it from a RL02 to a fake RL02. 
They should work, but only if you set them up to run at an address
different from the standard address for RLseries disks.

...
 How well do Boards with Boot ROMs co-exist with systems
with another set
of Boot ROMs?  I'm threatening to throw the DQ606 in the 11/23 that I'm
working on, so I can access the rack of drives that go with the
controller. 
Depending on the boot rom, a standard address is 773000.  You can't have
two sets of boards which respond the this address (and there isn't a
standard I am aware of for assigning alternate boot code to an address).
On systems which I have configured which had boot code on the controller
card, the standard boot code had to be disabled.
