Have you seen the two pole pin header on right side of the sub board? Is for this exact reason.
You must make first a small coaxial cable ended at both sides in a DuPont connector, as to interconnect it with the corresponding one in the main board. You can find this as a three pole pin header, behind the audio stacked connector.
We choose to proceed like this, to avoid the unwanted digital noise within PCB.

As for the XC12 tape corder, just now I see that it haven't a PSU, so must take their power supply entirely from eclaireXL board.
This mean that you need to supply the eclaireXL with a power adapter of 1 or 2A. I don't know how exact is the percentage of the current who need the internal motor of XC12 to work.

I think this explain why eclaireXL resets it self when you push the "PLAY" key on this specific peripheral.

Never heard again and think it works. Though I learned a lot more about how this should work since with Pokeymax v3 debugging...
