== The Vortex disc drive controller ==
The Vortex disc drive controler was similar to Amstrads own controller on DDI-1.
It used the same controler chip, the [[FDC|NEC765]].
It has [[VDOS]] on ROM.

== Germanized-English RSX Commands ==
Vortex considered the normal AMSDOS RSX commands |TAPE.xx and |DRIVE/|USER too difficult for german users, and changed them to |CAS and |SELECT - (which resemble equivalent german words ''Kassette'' and ''Selektieren''). This is making VDOS slightly incompatible with AMSDOS and all other AMSDOS clones (except for Dobbertin's X-DDOS, which supports both the english and germanized dialects.
