Abstract The Larry DeMar papers contain documentation on the creation of the Williams' pinball game Banzai Run (1988), as well as business cards from DeMar's career in pinball and the games industry. These photographs document component testing, prototype building, manufacturing, playtesting, and more. The engineering logbook, annotated by DeMar and Pat Lawlor, documents the development process of Wreck N Ball/Banzai Run.
