I got my first XT computer in 1990 and it seems like I know less and less as the time goes on. It seems like computers either get more complicated and I go the other direction on the learning scale. When in college I majored in broadcasting which included everything just about except engineering but half of my interest was in that direction. Anybody who has ever worked in radio could write a book on the weird aspects and people you meet. Of course I gues that could hold true of many professions.
