Hello,
I have a clone PDP11, including an SMS QBUS board and a 8" drive.
Not sure if it's the same model as yours.
The controller runs MSCP for floppy with RX02 or IBM format , and for an
MFM hard disk like Seagate ST251.
Board code is SMS FWD0106.
I should have some manual and drivers for it somewhere, if you manage to
find the board, but utilities like formatter aren't for VAX, IIRC.

The SMS documentation in bitsavers says the controller can be operated
in two modes; compatible and extended. In the compatible mode the SMS
unit will work with the DEC DY driver, or so they say. If that is true
that would be good news since my disk drive hardware has only 2 floppies
and no winchester disks. However, it looks I would need the SMS
diagnostics or FW driver in order to format RX02 media.
Nevertheless, if I do get it running and it is DEC RX02 compatible I
would try to use it in the MicroVax just to see what happens....
