Thanks for your answer but my Colecovision is PAL and this is not the same motherboard as shown in this link.

Thanks for all these info, now my ColecoVision has an AV output.
However, I would like to make a RGB (peritel-scart) output.
How can I convert Y, R-Y, B-Y signals to RGB?

Did you get your A/V output to work?

We tried it too but it blew up my Coleco...

Were did you get your info from?

My Coleco works with AV output but it was a NTSC unit.
The RGB encoder was related here.

This is the "PAL SECAM CONVERTER" in my french ColecoVision. This unit convert Y, R-Y, B-Y signals to RGB.

Thanks for the info!

The Ti99 used a similar chip as the Colecovision and the PAL versions of the TI99 were available with a SCART adapter unit (I have seen this adapter in Apeldoorn at the Retro fair, alas the keyboard of the accompanying Ti99 was bad so I did not buy the set).

I have tried to connect both of my Ti99's (I have a PAL & NTSC unit now, one had bad DRAM) to YUV inputs of several monitors without luck, the signal is not compatible. The NTSC version does produce a nice color image on its CVBS output and the PAL machine works OK with its modulator on the RF input of a TV. (but no RGB or YUV)

So maybe if you can find such a TI99 RGB adapter you can use it on the Colecovision

This is my AV mod for PAL Colecovision

AV mod on both systems, let's compare !
