Thanks to x993231 and Gates
I had to stop eating my bagel and ignore the dog while watching the video. After watching the video, then reading the MIT articles, and THEN reading your post a few times, my coffee and bagel were cold and I was glad there was not going to be a test. Actually, I think I am beginning to grasp the concept. So Indigo Perk is the secret sauce instead of germanium, and it is a monolithic chip? Geez, I hope that is right.
