How Old school Sound/Music worked

There is nothing in the world better than the old game consoles. NOTHING I say. For all of you born in the 80s or even the 90s, here's a little gem, from nerd to nerd, about how Sound and Music worked back in the old days. With the hype created by Stranger Things (the new Netflix series) about old stuff, It's good to go back in time when those things were the present. And just for you information, i still own a Sega Master System with some games and the gun that never pointed in the direction you wanted to.
