The PAL Amiga generates 256 lines as default in non-interlaced mode, and 512
in interlaced mode. The other 113 lines form the display border (in the 
background colour of the vertically highest screen).

The height of the display can be changed using overscan modes (which under 2.0
can be set from a preferences file).

Howzat?
