| 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.
