The Satellaview was a satellite modem released for the Japanese Nintendo Super Famicom in the not so distant 1995. It had games broadcast to it episodically (!) and is now considered a quirky little add-on for Nintendo's 16-bit console, that, really, isn't all that common outside Japan. You can find out more about the Satellaview here and here, and then grab one via Play Asia. By the way, what is it with Play Asia retro hardware being so popular?
