I recently acquired a Sega Genesis with Sega CD from a yard sale. I'm new to the Sega CD and it didn't come with any directions just a game and a few other random cd's. Here's my problem. I can't for the life of me figure out how to work it. There seems to be no on/off switch and I'm not even sure if it works at all because when it is plugged in there are no lights indicating it's on. Any help would be greatly appreciated!
