Page Mill Road entrance

In 1960, when Hewlett-Packard built offices and a new boardroom at 1501 Page Mill Road in Palo Alto, Calif., the facility was state of the art and evoked the new frontier. Now, it's a nostalgic reminder of a time when people smoked in their offices and nearly every available surface was covered with simulated wood paneling.

HP doesn't throw out a lot--the 20-foot table in the main conference room today is the same one the board used to meet around. The offices of deceased co-founders David Packard and Bill Hewlett are still intact too. We took a tour this week and here's what we found.

Is this a ride at Tomorrowland? Is it a pancake house somewhere in Los Angeles? It's the entrance to 1501 Page Mill Road.
