Changes

These are the latest drives from Vortex for use on CPC 464 with DDI-1 or CPC 664/6128 computers (ie. on computers that already have a FDC), so no own FDC 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 strong. They are housed have solved many of the problems, especially in a metal case with power supply (which has good protection with fuses) and have good quality drive mechanisms. The drive has jumpers on it that can be configured as neededterms of compatibility, of the earlier series.
