Hi. I just post thread about my broken Macintosh SE... Because of the working-well monitor, I want to try if the CRT can be a monitor that can be used to be AV monitor or something else? Just CRT is the hardest I think. Others can be done easily. I found the schematic and took photo of the yoke board (or socket board??). I want to ask if there're any open source program on GitHub or other website? Are there any like Gerber file or 3D print file??
