AI-assisted summary

Description from the seller

This product is a set of 5 Casio fx-140 scientific calculators that are malfunctioning. Manufactured by Casio Japan around the 1970s, these are classic LED display scientific calculators from the late Showa era. The calculators are marked "CASIO fx-140 10 DIGIT SCIENTIFIC CALCULATOR" and were commonly used by students and researchers at the time as 10-digit scientific calculators, supporting trigonometric, logarithmic, and exponential functions. Currently, all 5 calculators are malfunctioning and cannot be turned on or used normally; the calculators also show varying degrees of wear and tear.
