This series houses disc diagrams, wiring diagrams, parts diagrams, circuit diagrams, notes, instruction drafts, and more. The materials in this series are filed alphabetically in boxes/folders or in rolled storage boxes. When possible, the drawing type is indicated after the game title in each folder.

Folder titles are retained from the original transfer to the museum. For example, an abbreviation such as “B.A.” means “bowling alley” and “S.A.” means “shuffle alley.” Spelling of words is maintained from the original documents. Most materials do not indicate the original creator of the document.
