A great opportunity to see some of the pioneers of personal computing talk about their work.
Oh, neat that they’ve recovered the videos. I’ve read a number of these papers, which have some very good stuff in them, but had obviously never seen the talks. Contrary to usual ACM DL practice, the proceedings also appear to be open access (click on the “table of contents” tab).
Note that they have some great brief excerpts / highlights linked inline if you scroll down past the list of talks.
