DarthVaper Posted August 19, 2018 Author Share Posted August 19, 2018 tried on my other Atari 5200 this diy mod, but the only thing thats works is audio out... I tried this schematic, but no luck http://retrogame.cyberphreak.com/2017/06/05/atari-5200/maybe somebody has done this successfully and can send / show his soldered pcb (both sides). Thx... Still in the thinking to throw it all away and keep only the commdore stuff Quote Link to comment Share on other sites More sharing options...
