Slide Rule & Calculator Museum
Finally, a few of the cardboard calculators I have are at the bottom. Probably only the VSWR Calculator from M/A-COM can be considered collectible. My good friend Patrick Fitzgerald bestowed it upon me when I went to work for him at General Electric right out of college. I can recall some of the older engineers still using slide rules there when I arrived in the 1980s. In fact, the first algebra textbook I had in a community college right out of high school in 1976 had a section in it on how to use a slide rule. The Sterling 684 plastic slide rule that I bought at the bookstore is show below. Shortly thereafter, the HP-35 hit the market and the world changed forever (now that was truly a disruptive technology).
