The demo simply uses the same basic commands, but send them to both the NTSC and VGA monitors.
Summary
This demo shows how easy it is to get both NTSC and VGA terminal like text output going on the Chameleon.
28.1.6 VGA Star Field Demo
The default2 VGA driver isn’t as impressive as the NTSC driver. In fact, it’s pretty boring. It’s good for displaying text and
acting as a terminal output, but that’s about it. However, with a little ingenuity we can make it do some cool things! This
little demo, draw stars on the VGA screen on the last display line, this causes the screen to scroll and presto – animated
star field! Then on top of the star field a little character based ship is drawn. Figure 28.6 shows the demo in action.
