That controller looks just like one one I have, which connects up to an
8" hard disk and an 8" floppy. I found docs for it on bitsavers and one
other place (so the docs exist).
I'll go look at my controller monday and see what numbers it has on it.
I could swear someone on this list talked about that controller and the
rev of the proms on it several years ago (maybe 1-2).
The one I have has a boot prom; I don't know if it's rx01/02 compatible.
I've powered up the winchester and it comes ready but I have not tried
it with the controller (plan to this winter).

One of the boards (SMS le interface) looks like
an interface to a
disk controller. SMS made a dual disk system that had a 8" floppy
and an 8" hard disk in a 3RU cabinet. The system has a controller
in it that connected to the host via a 40 pin ribbon cable.
I think the "le interface" is the host end of that connection... I still
have one of the disk cabinets and controller. (somewhere)
Documentation for the winchester/floppy subsystem would be a nice thing to
find.
SMS made several different subsystems in the 80's with that interface which
weren't always compatible with DEC controllers.
I have some documentation on the FW series under sms on bitsavers
