Changes

These are the first generation of disc drives from Vortex. The interface supports either a single ("S" variant) or two ("D" variant) 80-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.
