Hi Folks - just some updates on getting my Atari 5200 to work. First off - my buddy created a STL file for me to print to replace the access door on the back so that i could easily mount the DVI port. Then i ordered some parts to make a test DVI/I - SCART cable so I could run it into my PVM. To my surprise, the first time I turned it on, voila - an amazingly crisp beautiful picture came up! Since the angle is downwards I think I will get a DVI extension cable and then wire up the DVI/I breakout board to the SCART with a small amount wire (almost like an adapter) since the DVI extension is what will get me my distance. Next step is to get audio out of the board to send it to an RCA jack on the back, and wire that into SCART connector for sound.
You have to (at least on mine) work a little hard to get the back access panel off, and this new one you have to push pretty hard to get it to snap in, but then it's there and not moving!
