== S- and D-Drives (720K/disk) ==
These are the first generation of disc drives from Vortex. The interface supports either a single ("S" variant) or two ("D" variant) drives having 80 tracks. Additionally, a 3" [[Amstrad Disk Drive|FD-1]] can be connected as third drive, ie. unlike most other CPC disk interfaces it supports more than 2 drives. With [[VDOS]] only two drives are accessible at one time. These drives interface with their own FDC can be used with the CPC 6128 to use different I/O ports (see below).
TO BE CONFIRMED: Does the interface fully decode US0/US1 from NEC765 and if you select unit 3 which drive is accessed.
* '''F1 - S''' Single 5.25" drive with power supply connected via ribbon cable to interface with [[FDC|NEC765]] and [[VDOS]] 1.0 or 2.11
* '''M1 - D''' Double 3.5" drive with power supply connected via ribbon cable to interface with [[FDC|NEC765]] and [[VDOS]] 1.0 or 2.11
