Born in '82 I didn't discover star wars until the early 90's renaissance (I had a very generic knowledge that it existed but didnt really know anything about it)
As for the 80's though, I have lots of memories. Cartoons in the eighties were AWESOME. Transformers, G.I. JOE, Thundercats, Voltron, M.A.S.K., Muppet Babies, He-man, Shera, Jem (yeah, even the girl cartoons were awesome!). It was a great time to be a kid. And I LIVED for Saturday mornings. It pains me that my (future) kids won't grow up looking forward to the incredible thing that was the Saturday morning cartoon lineup on network tv. Looney Tunes/Merry Melodies were always a highlight.
Also thinking about tv, I remember sneaking peeks at MTV at my grandparents (the only people I knew who had cable). It was a rare thing, but was consistently the most mind blowingly cool thing ever. It just oozed cool. And then I saw Michael Jackson's Thriller. Ho-ly crap. Utterly terrifying and incredibly awesome all at once. Mind blown.
I also have lots of fond memories of all the awesome toys from the eighties. Robots that did stuff (transform, combine to make bigger robots) were all the rage. Transformers and Voltron were big names. Pretty much all the cartoons were basically animated toy commercials so they all had their tie in toy lines. Oh, I had a Rambo Big Wheel.
As for tech, I vaguely remember atari, though we never owned one. Our friends down the street had a cd player, which my sister and I had no idea what the heck it was. We called the CDs "shiny records". We eventually got a Nintendo, but it was several years after its initial release (maybe even the early 90's). My dad was an engineer and he got a Hewlett Packard 286 at some point.
I also vaguely remember going to classic Disney re releases like Bambi and Pinocchio at the movie theater. I also remember seeing Song of the South air on tv before it got locked away. And 1989's Batman became an obsession of mine. I wasn't allowed to see it until it was aired in edited form on network tv but I had ALL the toys, bubble gum cards, etc. I was introduced to Batman via the Adam West reruns they aired on weekday afternoons in the 80's.
It's tough for me to separate the eighties from the early nineties b/c my childhood spanned them together.
So yeah, I was basically a child pop culture sponge, soaking up all the commercialism of my childhood. Ha!
