History and Timeline of PHOTO-Etched circuts?
Pre 1960's , Transistors were the future, right? tried to explain to the kids about the much bally-hoood terms of having a 8-transistor radio to sneak listening to the world series while in school (don't ask!) and how the tech of radios has changed in the last 35 years or so......With the coming of the electroniics revolution of the 70's present, any good sites or ways to tell the kids ( in their terms) that Walkman's and I- pod's and pentiums were always not the norm?
