The common standard inexpensive IDC connectors do not fit the hole pattern on the board. Once you add the $30 connector it provides the standard IDC connector for a ribbon cable. >From a posting by Timothy 2007-03-27: TNM> Subject: Re: [Open-graphics] General Purpose I/O Connector TNM> The hole positions don't line up with the pins.

I still don't know why the $30 connector was chosen rather than the cheap (US $0.40-$1.20 quantity 1) connectors. Perhaps due to board real estate, or signal routing issues? Too late now. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
