This is a used Sega Mark III that has been stored at home for about 40 years. I don't know if it works properly. I can't confirm because I don't have any software or cables. Therefore, please purchase it with the understanding that it is a junk item that may not work. If you don't have much money, it's best to refrain from buying it to avoid financial damage. There is no switch box, RF cable, or coaxial cable to connect it to the TV. There is also no antenna tuner, but this is for connecting to a TV antenna and is not necessary for the game. *However, it seems possible to connect and play games using a Mega Drive connection cable. The output is different, so it's slightly brighter, according to the explanation online. Even if it doesn't work, you might want to keep it as a collectible antique for display. It seems to be powered on, but it lights up even when the power switch is off. The power cable seems to be fine. Due to long-term storage, the styrofoam inside has melted onto the cables of the controller, etc., like a candle, but I have removed it as much as possible. The main unit has also been cleaned easily. Shipping from Northern Kyushu.
