The prototypes built by Leibniz and Pascal were not widely used but remained curiosities until more than a century later, when Tomas of Colmar (Charles Xavier Thomas) developed (1820) the first commercially successful mechanical calculator that could add, subtract, multiply, and divide.

HISTORY OF COMPUTERS Historically, the most important early computing instrument is the abacus, which has been known and widely used for more than 2,000 years.
Another computing instrument, the astrolabe, was also in use about 2,000 years ago for navigation.
The difference engine, although of limited flexibility and applicability, was conceptually a great advance.
Babbage continued work on it for 10 years, but in 1833 he lost interest because he had a "better idea" the construction of what today would be described as a general-purpose, fully program-controlled, automatic mechanical digital computer.
Artificial intelligence, virtual reality and enhancing the physical modelling of the real world are always a “little black dress” of computer science, they are always popular and there is a lot of data connected to them – but there are dozens of people writing about them and it will be really challenging to compete with them and write something completely new.
You may abandon the easy way and find something that is not so popular, but is very useful for some practical reasons: for example, making the complicated calculations faster, or perfectly modelling some tricky bacteria that biologists desperately need.
Built-in operations were to include everything that a modern general-purpose computer would need, even the all-important "conditional control transfer" capability, which would allow instructions to be executed in any order, not just in numerical sequence.
The analytical engine was to use punched cards (similar to those used on a Jacquard loom), which were to be read into the machine from any of several reading stations.
It was designed to operate automatically, by steam power, with only one attendant. Various reasons are advanced for his failure, most frequently the lack of precision machining techniques at the time.
Another conjecture is that Babbage was working on the solution of a problem that few people in 1840 urgently needed to solve.
