Here’s the world’s first calculator with CMOS chips from 1972 [video]

We sure have come a long way with electronics, haven’t we?

Even that functionality has been replaced by other apps.

As you watch the demonstration below, you’ll notice that this Sharp EL-801 was pretty darn small compared to the calculators that were tied to your desk. It was a revolutionary advancement in technology using silicon chips. It was the world’s first calculator to use CMOS (Complementary Metal Oxide Semiconductor) chips that are used without second thought today.
