Philippe,
It looks great, nice job.
Is that a Salota motherboard?
I'm curious about the ribbon cables between the SMB and the TIL311 board. When I visualize a flat cable with IDC connectors I don't see how this works? With one set of IDC connectors on the front of the SMB and the other on the back of the TIL311 board the even/odd pin rows should be swapped. Do I have this wrong or did you need to twist each odd/even wire pair to get it to work in this configuration?
