    I got my first calculator in 1973-it was a Texas Instruments with just four functions, and not even a square root key, but what a revelation that thing was-it freed me forever from the slide rule I had then been using in college. back then, every physics-related exam had log tables and scratch paper stapled to it. That TI was an object of curiosity that term-people who had never seen one stopped and checked it out. It cost me $75, and I still have it-it still works,too.
