I don't think anyone's that foolish ...
there has been legio posts showing something not applicapable to a given design applied with the question "It says it works, why does it not work for me".

Since he's playing, there's no point in telling him he's better off playing tiddlywinks when he wants to play pingpong
if someone wants to play in the snow, I would not suggest as a first game to try a 40m ski jump.

There has been a host of beginners that, since they had some old part in a drawer, wanted to start with a design far more complex than it would be with a suitable chip. Suggesting that someone start of with the intricacies of external memory, let alone swichable (as has been suggested) is ridiculous. I merely say START WITH SOMETHING SIMPLE.
