Funny DEC trivia, their "personal computer" ran a variant of RSX-11 called "POS". The joke on campus "It runs POS, and it is." It had some ungodly co-processor to run DOS or CP/M or something too. Mostly I've pushed it out of my memory. Second, the book "Computer Engineering: A DEC View of System Design" is a treasure trove of information about early DEC machines and computer architecture in general. I have a copy that I got to get Gordon Bell autograph at a Computer History event. If you're interested in system architecture I can easily recommend it. Finally, Ken Olsen's inability to see how "personal" computers would change the world is pretty legendary. It is right up there with the folks who believed it would never be possible for someone to make a business out of flying people places.
