RAS

RAS provides services to setup raster (synchronized color changes) interrupts frames

Raster system provides default interrupt routines to change colors on the screen. You can also provide your own routines. Raster system uses a kind of display list where you can chain raster interrupt routines and associated data. The standard provided routines backup 68k registers but they use 'usp' hidden register to save the list pointer.
