- You'll be able to use Super-Hires mode, so the pixels will be even more
- squished (tall and skinny) than they are in Hires. Other modes require
- a multi-scanning monitor.

- There's only one ECS Denise (required for the new Super-Hires and
- Productivity/VGA video modes, and the new Genlock capabilites.) Agnus
- does *all* the Chip Ram addressing, Denise and Paula have no idea about
- the size of Chip Ram. Agnus just hands them the data.
