Maybe you should check out kickstarter.com,  a lot of projects get funded that way, it's worth the try.  An Android based console got funded 8 1/2 million dollars on there recently (they were only asking for like $900,000) and it's coming out next year for $99. Not saying you would get anywhere near that for Colecovision/Adam of course but something is better than nothing.
