Texas Instruments SR-10 "Slide Rule" Calculator

1-34	Texas Instruments SR-10 "Slide Rule" Calculator	USD19.95

This machine is a nice, working example of an early "slide rule" calculator, the SR-10 from Texas Instruments. More than four-function machines, but less than full-fledged scientific calculators, machines like the SR-10 often had some scientific functionality, including an exponential display, but missing other essential functions such as exponentials, logarithms, or trigonometrics.

This particular SR-10 is in fair cosmetic condition (silver trim missing in places, plastic yellowed) and working well. It comes with no batteries (old, corroded cells removed) or charger.
