Subject: [CDXAmembers] Old documentaries about lasers, fiber and the transistor
From AT&T archives here are two interesting videos. The first is a demonstration of lasers, and fiber technology.
The second is a 1953 documentary about the progression from the development of the vacuum tube to the transistor and predictions for the future.
Great for a rainy day between contests.
