Sega CD Question

Okay so I just bought a fancy new sega cd system off ebay for ten bucks however it was as is and had no cables at all. I was just wondering what all cables do I need (other than the power cord) to start playing games.
nothing, other than the Genesis

you may want a Mixing cable, but I didn't use one (Model 1 Genesis + Model 2 Sega CD)

Which version, btw, is it? front loading or top loading?
