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 or a floppy controller)CPC 664/6128. Since these drives do not ship with a special an own controller or a VDOS ROM, they do rely fully on AMSDOS and thus only 40 tracks can be accessed.

These are the latest drives from Vortex for use on with a CPC 464 with DDI-1 or a CPC 664/6128 computers (ie. on computers systems that already have a FDCfloppy disc controller), so ; no own FDC additional controller was required anymore. Instead, a ROM module was supplied together with the drive, which provided VDOS 2.0-X. Only single-drive variants were available. The |S command (for accessing a third drive) is no longer used, the new |X command allows to swap drive A and B (same as [[X-DDOS]] from Dobbertin). These drives are very well designed and have solved many of the problems, especially in terms of compatibility, of the earlier series.
