Using a DEC RM80 as a Massbus -> SMD interface

Hi folks,

I recently picked up a DIGITAL RM80 drive.
>From what I've read, this is a SMD drive based around the R80 HDA, with a
massbus to SMD bridge.

I have identified this component and the outputs indeed look like SMD.

Is there a way to use this as a SMD controller with 3rd party drives?
How would you format or set geometries?

Does anyone have more information about the RM80?
