If this is not the case (I will not know until I can see a wiring diagram or such) then they are retailing (without the expensive connectors I'll be using) the device for the cost it will take me to produce mine. If I do sell to other than just friends, do I have to charge sales tax? What are the legalities here? Do I need a CPA? Are there any other S-100 sound boards out there? Cheers, Gern -------
