To be sure the devil is in the details. I was in high school before the internet existed as a commercial application and new about ARPANET because my advanced electronics instructor was working on improving it for commercial application back in 1982. They barely could send text back and forth and manly it was used to connect up the different science project for the military.
It is extremely important that information be accurate and this was bugging me too. Glad you cleared this up and thanks.
