Nice job there.

I have a Dialog DQ614. It presents an ST506/ST412 drive as a series
of RL02 "drives". It does not have an onboard configurator; you have
to run an RT-11 app to set it up. It arrived with a dead Rodime drive
and I haven't had the chance to fiddle with it, but I'm _guessing_ it
saves its config info at the front of the drive since there doesn't
appear to be anything on the board resembling NVRAM (EAROM given its
age). There's a chance your board also requires an external config
Andromeda stuff, OTOH, has onboard config programs that you talk to
via a serial cable. I haven't configured one of those in 20+ years,
but ISTR it was rather trivial to do. I didn't see an obvious serial
port on your board, but if it had one, it'd likely be a 2x5 0.1" pin
header patch, potentially with one pin missing, a la DLV11J.
