The map area was designed for graphics purposes. However, no graphics routines were implemented other than a simple horisontal horizontal line-write that PipeDream uses. The map is the small area on the right hand edge of the screen to display a picture of what a page looks like in PipeDream, when printed. This region consists of between 0 and 256 pixels across by 64 pixels down. It is theoretically possible to have a 624 by 64 Hires screen, but with current information, graphics are limited to the map area only. It is possible, with extreme care, to write directly to the map memory, by accessing the HIRES0 character set, see the "Hardware layout of the map" section for further details.
