Does anyone here own or know of any NES hardware prototypes in existence? I see there's a lot of discussion about proto carts, but I don't see anything about proto NES machines. Same for the NES sites I visit. Is it just because they are rare?

Anyway, I think I found one. Not a physical one unfortunately, but a picture in a book.



Now this must be a NES considering the Duck Hunt game and the R.O.B., but apart from these it looks weird. Do you agree that this is a NES prototype? Does anyone know more about this kind of early NES hardware?
