Hi all, For a commercial product, which has to provide proprietary 4-signal connection between two external devices, I am tempted to use SATA connector= s and cable. They are cheap, mass produced and thus readily available. I looked into http://www.sata-io.org/ website and couldn't find any legal limitation to use SATA connectors for something not being actually SATA technology. Does anyone have a suggestion on where to look at to know whether this could raise legal problems?
