THE IMAGES DISPLAYED IN THIS DEMONSTRATION 
            WERE CAPTURED USING A VIDEO DIGITISER ON A BBC MODEL B.

        The files are a mixture of BBC mode 0 (640 x 256) and
        mode 1 (320 x 256). BGRAPH can be used to display files 
        which are larger than 640 pixels in width (such as those 
        produced by AMX art) by specifying the image width.

        These images will only display on a PC with a CGA, EGA, VGA,
        Herculese or compatible adapter.    

        When an image is displayed the colours may be changed as follows:
      
        For CGA and Herculese modes the + and - keys will rotate forwards
        and backwards through the available colour combinations.

        For EGA and VGA the space key will select the colour on the
        screen to be changed and the + and - keys will rotate forwards
        and backwards through the available colours and shades.


        Press any other key to display the next image.
