Changes

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-track drives (BASF 6138). 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).
