The PC Engine Core Grafx is a console that offers a classic gaming experience. - Model Name: PC Engine Core Grafx - Serial Number: PL-TG3 - Connection Port: Game Card Slot Thank you for viewing. I'm gradually putting items from my parents' house up for sale. My family says they tested it about two years ago and it worked fine. However, since it's an old item, please don't expect too much. I'm listing it as junk. It looks to be in pretty good condition. If you have any other questions, please send me a message and I'll answer to the best of my ability. Thank you.
