Well you will probably know by now there are 2 revisions of the bittboy V1 & V2 the only difference being is V2 is more user friendly installing the CFW. The way to tell externally is if you press the start & select buttons if they are soft its V1 if they have a clicky feel to them then its V2. If you want to dig a little deeper and make sure remove the 6 screws and on the top right where the sd card is situated you will see the words V2.0 or on v1.0 there is no marking on the board.
