What does this device do? Connects to the side then the pad slots in the side of the device.... http://www.japangamestock.com/images/multibox-fami400.jpg http://www.japangamestock.com/images/multibox-fami400-2.jpg Has RF input or output on the rear??
Cool added that to the main....at first I thought battery back up or RF to AV output but from the looks doesnt seem likely?
It looks like that's an antenna coming out the back, maybe it was a low power transmitter so you could tune your TV to a certain channel and the Famicom would appear on there? Kind of like mr. microphone but for video
I believe it made your Famicom wireless. It contained batteries for a power source, and used the antenna to broadcast to the TV.
Wasn't the Satellite just a wireless Four Score? The Multi box appears to make the viedo signal wireless, which would be a totally different function.
