[NEDBIB-L] Charles Babbage Analytical Engine 28

Soms best wel aardig zich een klein beetje op de hoogte te stellen van
de geschiedenis van computers, al is het maar omdat zoveel rekenkracht
vandaag de dag zo gewoon wordt gevonden.

Hieronder een artikel over de (bouw van de) eerste 'echte' computer, de
Analytical Engine van Charles Babbage, waarvan wordt gezegd dat het
apparaat mechanisch dermate gecompliceerd was dat het in de negentiende
eeuw niet mogelijk was het machien te bouwen.

Let's build Babbage's ultimate mechanical computer

The 19th-century Analytical Engine computer, complete with CPU and a
memory, remained unbuilt – time to put that right, says John
Graham-Cumming

IN 1837 British mathematician Charles Babbage described a mechanical
computer that later became known as the Analytical Engine. Calling it a
computer is no stretch: the Analytical Engine had a central processing
unit and memory and would have been programmed with punched cards.

Parts of the Analytical Engine were built in the 1800s and are on
display in the Science Museum in London along with a stack of punched
cards. But Babbage never completed the project.

The computer was an extension of his well-known Difference Engine, which
was designed to calculate tables of numbers such as logarithms.
