Dial-a-Door technology to appear at Dork bot PDX tonight

About Us CTO, Ward Cunningham and his college roommate Rick Wartzok, had better than average audio/visual and beverage capability in their dorm room, at least for 1968. While happy to share with fellow residents, they then faced a dilemma. What about keys? They wanted some kind of combination lock that had a shared code that could be selectively enabled, and a longer, master code for private use. The solution was Dial-a-Door:

Now its 2008, forty years later, Ward has located the mechanical technology that decoded the combination, restored it to working order, and prepared a display which he will present at the bi-weekly DorkbotPDX tonight at the Lucky Lab in Northwest Portland. Here is About Us colleague Stephen Judkins inspecting the device.
