A friend who used to work as a software trainer for DEC sent me the following link (https://m.youtube.com/watch?v=uIqlMfSCs0E), which points to an hour-and-a-half-long YouTube video from June 2021 about the history of DEC. It is a Zoom presentation from the Maynard Public Library done by a local newspaperman. It is fairly general, but was attended by a number of former employees, some of whom made comments.
