I have developed a new version of the RGB converter for Atari 2600, more compact than Eddy Foucault's version, which is soldered directly onto the TIA, on the back of the Atari 2600's motherboard.
There is fewer solder joints You still have to solder 3, not to mention the SCART cable, compared to the previous version, so it's quicker to assemble, but the soldering remains delicate. Best reserved for those who are adept with a soldering iron.
This RGB converter is available in two versions depending on the TIA chip in your Atari 2600: PAL-SECAM (in most cases) or NTSC.
