Changes
== X-Drives (720K) ==
These are the latest drives from Vortex for use with a CPC 464 with DDI-1 or a CPC 664/6128 (ie. on systems that already have a floppy disc controller); no 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 problemsof the earlier series, especially in terms of compatibility, of the earlier series.
