Does anyone here have any general knowledge of black-and-white TVs? I'm trying to hook up the PlayStation & Dreamcast but the TV is doing nothing whenever the socket is an input at the back :?

I went through a lot of trouble just to get this little TV mean my friend stole it out of an abandoned hotel, I had to trek across feels swing across a branch over a river... it's pretty ridiculous!

talking to some older people the answer I'm getting is that the range from the Dreamcast & PlayStation are different to what black-and-white TVs are meant to pick up, but I'm pretty determined run to get this up and running. wouldn't it be cool playing in black and white?
