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.
