    I have a French Colecovision and am currently trying to sell it on Ebay. Is it possible to obtain a adapter lead to allow the machine to output to a normal 21 pin SKART ?

    Hi David, you need the RGB Scart (secam) cable, it works Only if you have a Colecovision with RGB pinout on the rear side (photo #2)

    Hi first of all thanks for sharing this with us. And so after viewing these pics I thought you would be capable to help me here… I have the same model as described; it is a French colecovision with that video output but I can’t manage to get any sound from it. Right now I’m using it in Portugal does this matter? My region is pal-b.

    Thanks in advance

    Hello! :)

    Why did you take ground, composite synch and audio output from the mainboard when everything is there on the D15 audio-video output?

    I just opened my console, it was a pain but I don’t want to use RF anymore. I’m french with a french console. It seems some version was sold with a SCART lead cable, not mine!

    I don’t think that same original SCART lead cable could work with my console. And they are not cheap on Ebay, better to buy the console again but with the cable…

    I think I need to do that mod, but I did that lead cable done in ASCII, straight from the console 15 pins output to a SCART (I found D15 connector on ebay) and got only sound.

    Kind regards

    mi potresti dire come applicare questa modifica dei Component RGB anche al Colecovision Italiana (quella con solo l’ RF out)

    Questa modifica funziona Solo con il Colevo vision SECAM RGB. Non funziona con le altre versioni. Il chip video che viene utilizzato nella versione SECAM e’ diverso dalle altre versioni.
