Tru,
Good luck at the doctors. I have to go next month. As for the slide rule, I had a class in that in college and they would allow me to use it on the First Class FCC test, but since the answers to some of the questions had to be to the 5th digit past the point, I only used it to get the first 3 as it was very accurate to that point and then got the last two by a pen and scratch paper. I wish I knew what happened to that thing as most of the people around here that I mention it to don't even know what I am talking about.
