The VIC-II chip is the video controller chip used in the C128.</p> <p><img src="https://imgur.com/sffkCkt.jpg" alt="VIC-II"></p> <p><a href="https://en.wikipedia.org/wiki/MOS_Technology_VIC-II" target="_blank">Documentation</a></p> <p><a href="https://www.c64-wiki.com/wiki/VIC-II" target="_blank">Documentation</a></p> <p>The main problem was that the video signal was faded, dull, it was dificult to see the letters on the screen and in C64 mode the screen was almost impossible to read.</p>
