Columbus’ Powerpoint Presentation, 1987

This presentation was included with the first version of Powerpoint 1.0, so to speak, for demonstration and educational purposes. And «no», no one knows what Columbus actually said that day, it’s a fiction of the authors of the PowerPoint 1.0 (before it was acquired by Microsoft).
