First 5 Inventions based in Computer Technology: 

1^st Invention: The Antikythera mechanism known as

the earliest analog computer and geared mechanism shown below:

Reason of Invention: The prediction of astronomical positions and eclipses for calendar and astrological purposes.

Date of Invention: The beginning of the first century BC

Inventors: Discovered on 17/05/1902 by the Greek Archaeologist Valerios Stais inside a wreck at the coast of the Greek island Antikythera and was Invented by Greek ancient scientists.

2^nd Invention: The first attempt to build a computer with all the basic elements that never succeeded is shown below:
