I think this is no Prototype. Its a selfmade EPROM Cartridge, which play EPROMs. I own myself one.
You can easy burn with the right hardware yourself some EPROMs and play them on this cartridge. :/

So I think its no real Prototype.

the board is of course not a real prototype and not really a collectors item,even if it was build by an atari employee because you cant prove its authenticy.
some of the chips appear to be retail maskroms.
if the price doesnt go too high i'd buy it out of curiosity,chances are its a fake,but i somehow doubt that.
maybe theres a beta on the eproms thats not yet dumped,would be nice.
if you have some spare barebone protocarts,you can also use these eproms with em...
