    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 ?

    @David

    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
    Stephane

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

    Ciao,

    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.

    … che chip video avrebbe la PCB 91206?…sono curioso..

    Preciso che la versione PAL in mio possesso è come la tua “Francese” 91162 Rev.D, ma al posto di avere quello schedino di comversione PAL/SECAM (per poi andare a quello strampalato connettore con un groviglio di fili per poi andare in Scart TV) ha il sinto RF che miscela tutto (e dunque esco col cavo antenna)…quindi le tue supposizioni potrei confermarle… e aggiungo che se le tue foto della Rev.D illustrano la scheda così come l’hai trovata appena smontata: mi sembrano saldature postume : un adattamento in corsa (non certo un progetto “industrilale” ben fatto come con la 91206) quindi la cosa avvalora di più l’ipotesi tua…e che potrei cavarci fuori un RGBS dalla Rev. D…

    PS: mi hanno lasciato perplesse quelle saldature sui pin del connettore frontale di espansione (fili nero, grigio, vede, blu, marrone)..se mi dici dove vanno sullo schedino SECAM… GRAZIE
