The odds are there isn't a Q-Bus controller, even though the system

Is the 8" floppy by any chance a "Tandon Model TM848-2E" or "Model
YD-180"? I'm guessing what you have is out of an SMS-1000 PDP-11
based computer. They had their own board for the I/O, and the Q-Bus
plugged into that.
You can find a few pages from the manual (everything I have) at:

That's similar, but not what I have. the backplane and disk assembly
are separate.
There is a very large board connected to the HD & FD, with a 2901 and
8085. This appears to connect to something on the qbus with a 50 pin
cable.
