Not sure about the Magic 8 Ball but you hit everything else on the head.  Lots of neon!!!!    

Star Wars, Garbage Pail Kids, E.T., Michael Jackson.... Do a fingerless glove covered in Disco Dust!

Cassette tapes, walk-man's, Atari, Strawberry Shortcake ( the way she used to look, not the new teenage looking one )  

Troll Dolls!  I remember my sister had a BILLION of them.

Here is a website that might help,

You can look up a lot of things for what every year you would like.   You can look up toys, music, movies fashion trends, all kinds of stuff.  

Bubble gum jeans and DB's (desert boots) and cabbage patch dolls, tie dye shirts, big hair!

Omg-- you guys are the best!!! Such great ideas!!!! Whoo hoo- I can get started-- thank you for the link!!

Neon--- wasn't sure where that fit in -- so glad I can use it!!  Yeah I thought the magic 8 ball might been a stretch- I was starting to get desperate- ha!!
