Magic-Brain Calculator, purchased from a TV Guide ad in the 1970s. All it does is add and subtract things, but it does it without electricity, mechanically. It came with a stylus, but you can use a pen or pencil tip to slide the geared tabulators. When done, you zero it by pulling the handle at the top.
“The Thacher calculating instrument was patented in 1881. It was cylindrical and could slide back and forth, giving it the power of several individual slide rules. It could do multiplication and division, and calculate interest, roots and powers of numbers to about five significant figures. It was also accurate to within about .01%, incredible accuracy for that time.
