The Atari Coin-Op records comprise 600 linear feet of game design documents, memos, focus group reports, market research reports, marketing materials, arcade cabinet drawings, schematics, artwork, photographs, videos, and publication material. Much of the material is oversized.

This documentation on the Atari Cosmos game system was provided by Dan Kramer, former Atari Engineering staff member in the Consumer Electronics division. Materials include four hologram screens (two for Superman EG502, 1981 and two for Asteroids EG505, 1981) and copies of photocopied press releases and images of the COSMOS game system.

The Carol Shaw papers are a compilation of game design documentation, notes, sketches, source code printouts, advertisements, and other ephemera relating to the career of video game designer Carol Shaw. The bulk of the materials are dated between 1978 and 1984.
