Sorry for the noob question, but I figured someone on this site would be able to give me the information I am looking for.

I'm just getting back into classic gaming, but I'm not sure how to connect all these old systems (you know, the switch box with the 2 wires hanging off it) to a brand new HDTV with s-video, RCA, and component inputs.

I remember the old adaptor that you can screw into those that lets you plug it into a coaxial input, but ideally I would like to find a way to connect multiple "old-school" systems up to one switch box or something so I could have all my gaming on one TV.

Any suggestions or recommendations?

Cheers, and thanks in advance for the help.
