Great! It's just like a Mindstorms jack. There is also a "~" symbol next
to the 9-12V marking, which means you can supply any polarity you like.
They do, after all, have to make it kid-proof!
I'd recommend RadioShack 273-1656A. It's a 9V 800mA adapter and I use it
for Mindstorms work all the time. The older motors used more current under
heavy load, so it's worth a couple of extra bucks for an 800mA unit.
Good luck and have fun!
Cheers,
