Most of you probably heard of this website, but I just found it. It has some nice information about ..... Atari games, yes, including internal memo's and game manuals. If you remember the games that were (and still are) in the Belgian warehouse, at Atarigames.com you can find the manuals. Like Breakout, Super Break Out, Canyon Bomber, Video Pinball, Super bug, Atari Basketball.
A nice website.
