Those codes look rather interesting, I wonder how you're meant to type them in?

As for expansion, it has two external options, one is a four pin card slot on the front, under a trap-door, to accept a credit/cardbus card sized object, possibly a "key" to unlock more features? On the right side there is a very wide an bizarre port under a screwed on panel. It's vaguely reminescent of the duodock connector, may be not as wide, and it has a little pushbutton next to it, to sense that something is plugged in to it I assume. It's actually sticking out of the case, though, so whatever would be pluged into it would either be a very heavy cable, or a box mushed right up to the side.
