I'm looking at buying a Japanese Megadrive console and have one lined up.
The seller has sent some pics and it has the power in socket, the circular AV socket (into which my scart cable should go) and the EXT socket on the rear panel. However, it also shows a coaxial cable coming out of the centre of the rear panel!

Is this normal?
Will the AV out socket still function?
I need to know urgently as I have to decide whether or not to buy...
Thanks!
