And, per the open source hardware requests, here is a ZIP file containing a parts library for CadSoft's EAGLE schematic design software containing an ADC connector, VGA connector, DVI connector, and a few USB connectors. These are missing from the default libraries so one could edit and make their own ADC adapter board.
I had success wiring up the various connectors, but you may need to adjust dimensions to meet DRC requirements with whatever method you are getting circuit boards made. Naturally, there is no warranty with this library.
