Howdy-
After looking into various switchbox & other options, I've decided that the easiest way to hook up my classic consoles is to run an extension cable to the back of my receiver.
This cable should have 3 male RCA jacks (red, white, yellow) & 1 male S-Video jack on 1 end, and a female set of the same on the other end.
So this saves me from having to dig blindly at the back of my receiver when connecting & disconnecting different consoles, by essentially moving that set of connectors out to an easily-accessible place (no, my darn receiver has 3 RCA ports & an optical audio port on the front, but no darn S-Video...).
Know where I can find such a product? I haven't had any luck yet.
Thanks,
