Kind looks like it might be a Rodime, but could be CMI.
Keep in mind that, "formatting these for a PDP-11" can mean many
different things, depending on what controller you're using. Some
controllers, notably the DEC RQDX1 and RQDX2, cannot use drives of
arbitrary geometries. (at least from what I can remember)
