VDI
From Atariki
The Virtual Device Interface (VDI)jest zbiorem sterowników
designed to provide applications with a device-independent method of accessing graphically based devices such as monitors, printers, and plotters. Applications which are written to use the VDI rather than directly accessing hardware will be compatible with all currently available devices including those which have not yet been developed.
Wszystkie komputery Atari z systemem TOS w ROMiw zawierają ekranowe sterowniki VDI wszystkich rozdzielczości jakie dany komputer udostępnia.
Nowe sterowniki ekranu jak i innych urządzeń mogą być ładowane przez podsystem VDI nazywany - GDOS] Graphics Device Operating System.
