Steve Webber on Multics
This is a video of a lunchtime seminar about Multics features and history that Steve Webber did for Stratus employees in 1986. It includes comparisons of the features between Honeywell Multics, Stratus VOS, and to a lesser extent UNIX.
(Regarding the quality of this video, it is from an old SP VHS tape which was converted first to DVD and then to MP4 before uploading to YouTube.)
