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
