EC Calculator - 1980s

"After we've tested the calculator we either market it...or pick up the pieces"
says Mr. G.C Saxena, Quality Control.
That's because EC calculators are put through a series of humidity, dry heat, low temperature, vibration and bump tests that no other calculator manufacturer in India does.

I wonder if even computers undergo that kind of testing these days.
