Got the Sega Vectors working that have been giving us a bit of trouble recently. The Zector was giving us garbled graphics. I found this to be from the ribbon cable on the x/y timing boards. I do not know if it is the cable itself or solder joints as I have not looked closely yet. But moving this cable brings the picture back in. Certain positions of the cable will turn the picture about 45 degrees. I will pull the timing boards and take a closer look at the solder joints and ribbon cable and repair as needed.
