Hi Miguel, > The monitor used was a PS/1 VGA one, and I did take a photo (phone > camera) of the thing connected to a standard QL running in MODE 4. > This is what I saw: > > http://www.atc.us.es/~rodriguj/ql_composite_to_vga.jpg
Thank you. It seems that part of the screen is cut off :-( Also the picture seems noisy. By the way, that's why Thierry's statement "8 colours need no A/D neither D/A" should not be taken literally. Even if the digital resolution is only 1 bit, you still have conversion from/to analogue signals, and this requires exact thresholds, levels and very low noise. I remember a tinkerer who built an Atari monochrome graphics card and forgot this - his first PCB was in vain although the digital part was fine.)
