When I arrived at Texas A&M, engineers had been using slide rules for more than a century. As a freshman engineering student, I even had to spend part of the introductory course learning how to operate one!
For my part I came with an HP-35 calculator, similar to one shown at the right. Before same Jack K. Williams handed me my diploma, HP-35's and calculators like it had swept away the slide rules. Today calculators that do the same work and more of the HP-35 (which retailed for US$395 in the early 1970's) can be found in virtually any drug store for US$10 or less.
God has a sense of humour; after a great experience at Texas A&M, I moved to Dallas to work for HP's rival in the calculator business, Texas Instruments. It is our hope that this page will bring back happy memories--or at least afford you an online calculator when you need it. (A copy of the instructions on the back of the HP-35 is shown at the left.)
