btbfilms76 Posted January 15, 2018 Report Share Posted January 15, 2018 Well I’ve had a sick Roadblasters monitor since I acquired this a few years back. It was not great when I got it and little by little I watched it die slowly each time it powered on. I was loosing color and detail so I decided to switch out the old monitor with a 19in VGA monitor.... Well this became a tricky situation because unless you do a very deep information dive you migh run into some problems - as I did. But I figured it out and I’d like to share everything that I came up with. CGA/EGA/YUV TO VGA CONVERTER Is the piece you need to purchase but mine arived with no instructions so right away I needed to go searching online for them. https://www.mikesarcade.com/estore/datasheets/GBS-8200-booklet.pdf Mikes Arcade really had some great tips however the cable that came provided did not work... at all. I thought I had a broken board. The other problem is the video cables coming off the System 1 PCB were 7 in total and I only had 5 options on the new converter. So RGB makes sense - what about the other 4 cables? Where do these go? Luckily I found this “The Scamatic Packet Suplement for the Atari System 1”. Now I’m able to see exactly what each color means. So instead of using the cables provided with the converter I soldered them directly to the board right at this point here. I used RGB Black and Brown.
