Most games come with a fairly decent soundtrack, and you can often drop music files into a designated folder and the game will play your music. I like to cruise down the highways of America and Europe in my big rigs in VR listening to Frank Sinatra in, "American Truck Simulator" and, "European Truck Simulator 2".

That'll get you started. 1988? Well, that's been a while. I can't remember what I had for breakfast this morning, but I remember 1988 like it was yesterday, LOL!
It was probably all those vacuum tubes and the hurricane fan to cool them that made that portable Compaq so heavy back in '88.
