DVI Text mode


Working towards textmode terminal on DVI display…

DVI text mode on monitor

Based on modified colour_terminal example.

Screen mode is fixed to 768x480@60 with horizontal line doubling. Effective resolution is 768x240px, which will be used later for CGIA implementation. Colors are RGB222, which is more than enough for VGA-like terminal emulation.

Unfortunately, I see no way of implementing interlace mode, which would allow for full 640x480 CGIA resolution. There is a post on StackOverflow with details. Maybe you could chip-in ¢2?
