I am not going to scan the whole 200 plus pages of the manual, so, since parts of it are already on the web I will provide links instead. You may also be able to purchase a copy of the manual from Video 61 who are the current copyright holders. The 7800 Game Standards document, 7800 software guide, and 2600 programmers guide can be found at the Atari Documentation Depot. The overlay for the keyboard controllers can be found here. The schematic for the NTSC 7800 in four sections are upper left, upper right lower left, and lower right. (Large files) The game manuals for the 2600 games can be found here.
