It's remarkable how much influence Domain/OS and Apollo had on later computing and how few people actually remember them. I have an HP 425t here with a Domain keyboard port, but after someone upgraded it to a PA-RISC 715, the keyboard port is no longer connected to anything internally. Somehow this seems metaphorical. I also remember their computer graphics division. "Fair Play" made the rounds at a lot of CGI festivals around that time.
