how do you do a Component mod

Just wondering if anyone knows how to build a component mod for the NeoGeo. I have seen that people are offering it but are still in production I guess. Any ways just wanted to know if it can be done with a diagram and a parts list if anyone has that info and was intrested in sharing the knowledge? Thanks to anyone that may have some insight into this.
Have a good one.

Well, more than a mod, you have to install internally or externally a small board like JMKurtz's Neobitz that converts RGB into Component.
