I bought the BSD history video last year and I enjoyed every minute of it! Probably my best "geek" video..
You get this 2.5 hours talk from Dr McKusick, with his personal account of the BSD history. His talk follows his paper in DiBona book (
twenty years of Berkeley Unix).
And yes, I really enjoy his comments about working with Bill Joy ("hack hack hack hack"..) and his personal recollection of the AT&T lawsuit.
As an extra, I got his personal signature on the package (for the custum declaration since I'm living in Canada)..
Man, I'm really a fan!
