Changes

These are basic and less expensive ''low-capacity'' drives and were meant to be directly connected as B drive to a CPC 664/6128 or CPC 464 with DDI-1 (ie. on computers that already provide a floppy controller). Since these drives do not ship with a special controlleror a VDOS ROM, they do rely fully on AMSDOS and thus only 40 tracks can be accessed.
