I saw the schematics for this adaptor:

and it looks awesome but my solder/technical skills really suck nor do I have the time so I want to find someone that will build this adaptor for me. It will allow me to use my Jaguar controller with Atari 5200, Colecovision, and Intellivision.
Please PM me and name your price!
