Early 3.5" disks had a manual shutter, you had to

couldn't take the now-standard disks with automatic shutters because they
lacked the lever to open the shutter.
Was this universal? My Sony 2/3 height drive (40 cylinder, single side)
will accept the shuttered disks just fine and it's about as early a 3.5"
drive as one can find.
