(There's no video for SGI OpenGL 1.1.2 yet. Please contribute to MR and add a video now!)
OpenGL 1.1.2 was one of the earlier versions used in the Mac OS 8 era. It could be downloaded from Apple's FTP at some point.
For any Mac OS version above 8.1, it is suggested that you use a more recent version of OpenGL than this.
