It took some searching, but I knew my OCD-adled youth wouldn't have allowed me to throw things away.
Found my old collection of 2600 manuals at the parent's house over Christmas. I think these were most of the games I got new....majority of my games were purchased used.
The best part was the different game catalogs were filled with circles and X's so that my parents would know which games I wanted on my future Christmas lists (and thinking back, I don't think they ever actually bought a game off of my lists anyway....)
