Video generator for old BW monitor

Beke Andras has an old monitor which needed some repair. So he decided to build a video generator for it. This monitor uses different signal than composite so he started investigating the problem. He took a dsPIC30F301 based board and started prototyping. Later this grew into PCB designed with Geda software.

Despite its different control, monitor still needed same horizontal, vertical and video signal. With a bit of code he was able to generate static images and moving characters (running horse). He used small special programs to draw static images and generate motion picture. Beke faced a small problem with horizontal size, and he hopes that someone with tube knowledge could help to solve this issue.
