I still have my original HP-35 that I bought back in 1972. I waited for months for my pre-ordered unit to arrive, and I was the first kid in my whole Junior College to have one. It was a very liberating experience to be able to "CALCULATE" any math problem to a whopping 10 digits of accuracy with a dynamic range or 9.99999999 E 99 to 1.0 E -99!!! Until the advent of the HP-35 this kind of computing power was only possible on large desktop units, or mainframe computers. Slide Rules couldn't come close with their 2-1/2 to 3 digit accuracy, and you still had to keep track of the decimal point and powers of 10 manually. It was truly REVOLUTIONARY to carry this kind of power in your pocket.
