Is CBS Colecovision supported by OSSC?

[Mister Fab]

Hi,
I just bought my first Oss and it works perfectly with my PAL Snes, but I can’t get an image on my 65″ philips with my PAL CBS Colecovision (scart). The signal is sync and detected on av1, and I can hear sound.
jas someone got an idea?

The OSSC requires either YPbPr or some form of RGB, and the OSSC acknowledging sync, but providing an otherwise black screen, generally means either your SCART cable is only wired for composite video (not uncommon for SCART in general) or your console only has a composite video mod installed, not an RGB one.

Thanks for the answer.
I checked the wiring, and the Colecovision uses csync, and no pin out available for Luma.
I hope I can find a way to modify the console to get a usable signal.

I’m not sure I understand. So the console does have an RGB mod? And the cable is fully wired (Read: it has pins for RGB, not just composite video/sync)?

[Mister Fab]

Yes, the cable is RGB wired. It is the original cable, my father bought the console in 1983.
It has a SCART (Peritel in France) to connect to the tv and DB15 on the console side.
So as I understood while modifying my SNES cable is that the RGB can be sync by Luma or by Csync.
But the Colecovision doesnt seem to have a luma pin out.

It is wired like this:

If it’s the original RGB then it’s probably just a rough conversion of composite video output and won’t give good results. I’ve only tested a true RGB modded NTSC unit and it seemed to work well or me so there’s nothing inherently that stops Coleco working when properly RGB modded.
