DY probably refers to the RX02 floppy disk drive, since I think
that's the two character code used to boot an RX02 on a unibus
system M9312 bootstrap/console emulator.  Perhaps a controller?
Maybe you already have the disk controller you need.
Does it have a connector to hook up a flat ribbon cable. I don't
remember off the top of my head how many pins are on the cable,
but I just hooked up one for an RX01 drive/controller a week or
two ago.

And if DY represents the RX02 drive, surely RK represents the
RK05 drive as you are guessing.
