All that the AutoScroll feature does is make the visible part of the screen into a viewport onto the larger bitmap held in memory - just like the Chaos Engine, etc.

The only reason that you are not normally aware of the fact that you are looking at a viewport (which you always are doing in any case) is because the viewable area is the same size as the displayable screen area - so no scrolling ever takes place.

The biggest visible size that you will ever get without higher scan rates is standard PAL with max overscan - 724 x 283 non-laced (ignoring SuperHiRes unless you have a very-wide-screen TV hooked up). If you now define an oversized Workbench then that becomes the size of the viewport onto the bigger displayable area.
