RE: Your First Handheld?
My first hand held was Alice Tomlinson's in the 5th grade.
Oh, I guess that really isn't the topic. When I was a senior in high school (1974) my dad gave me a Commodore MM-4s. The "s" indicated that it did square roots, I think; it was not a scientific calculator. It was clear after a few quarters in college that I needed something a little more worthy. I coveted my neighbor's HP-25c but the TI-30 cost a lot less, so that is what I got. I know, it was not in the same league, but my budget at the time had to account for girls and beer too. I seem to remember that the TI-30 didn't last through school before it gave up the ghost. I used a few credit card sized calculators attached to my "Rite in the Rain" field book to help with basic math for timber cruising. I also bought a TI financial calculator sometime early in my career, but I don't remember the model. In the mid '80s I asked an engineer with my culvert supplier to help me with a stream flow study using depth of water in a free flowing culvert to measure stream flow, and he used a HP-41 with a Manning flow program to do it. About that time HP-41s were starting to be used in other forest engineering and forest management problems an I decided that I needed one.
