Ok,  a first try, please tell if this exist...
 
Also, should we use raster or maybe other terms ?
 
Concepts : Raster, split raster, Raster lines or Scanlines ?
 
  
In programation, the raster is often referred as the act to modify the setting of inks between 2 scanlines.
 
 
This is a way to display more than the usual [[Video modes]] number of colours.
 
 
The time between the display of 2 Scanlines by the CRTC allow the CPU to order the Gate array to modify the setting of inks.
 
 
The screen display at 50Hz...The [[CPU]] ([[Z80]]) runs at about 4 MgHz.
 
 
So It has enough cycles between 2 scanlines to order this.
 
 
You can also use Split rasterto "actually" display 2  different screens, sometoimes with different Video Modes.
