The GDA-1 is a full length Zorro II graphics card designed for use with their Amiga X Window system called Gfxbase. The X Window System is a graphical environment popular on UNIX/Linux operating systems, which has the advantage of being able to show it's windows on remote displays. There is no support for using this card for more 'coventional' means under AmigaOS and in particular there are no RTG drivers. The card is however supported under Commodore Amiga UNIX, affectionately known as Amix.
