The Mark I was invented in 1937 and built by IBM. It took five years to build (five years?!) and was assembled at Harvard University in 1944 and used by the military (of course!). It consisted of 750,000 parts. It weighted five tons, fifty-one feet long and was eight feet high.
In 1967 Texas Instruments built the first hand-held electronic calculator.
The first pocket size calculator the Buscicom LE-120A retailed for $395 in 1971.
The TI-2500 DataMath calculator sold for $149 in April 1972.
In 1981 TI introduced the first solar powered calculator, the TI-2500 and sold for $149.
The term "computer bug" was coined by programmer Grace Hopper in 1947 when she fund a moth stuck inside Harvard's Mark II computer.
Personally, I hate to admit it but I actually believed computers were a mere passing fancy. True story.
