PC Engine DUO console PI-TG8 Controller Adapter Stereo cable This is a set. Please check the condition from the photos. The stereo cable and adapter are also genuine NEC products. I have confirmed the operation with Hucard and CD-ROM. I don't know the standard volume, but it doesn't feel small. The headphone jack has also been checked. Saves are currently working, but the remaining backup capacity, etc., cannot be guaranteed as it is over 30 years old. It is currently working normally, but it is treated as junk because it has not been maintained. When purchasing, please refrain from purchasing if you are nervous, as it is an old item and may have dirt, scratches, discoloration, label deterioration, etc. We are sorry, but we cannot accept cancellations or returns after shipping to prevent swapping. (To prevent swapping) Please purchase only if you understand the nature of retro games and that they are used items. PC Engine Hucard CD-ROM2
