The left end consisted of electromechanical computing components. The right end included data and program readers, and automatic typewriters. The Harvard Mark I, or IBM Automatic Sequence Controlled Calculator (ASCC), was one of the earliest general-purpose electromechanical computers used in the war effort during the last part of World War II.

It was the first calculator that could perform all four basic arithmetic operations. [ 3 ] Its intricate precision gearwork, however, was somewhat beyond the fabrication technology of the time; mechanical problems, in addition to a design flaw in the carry mechanism, prevented the machines from working reliably.
The first model of the Arithmometer was introduced in 1820, and as a result Thomas was made Chevalier of the Legion of Honor in 1821. [ 2 ] [ 3 ] Despite this, Thomas spent all of his time and energy on his insurance business, therefore there is a hiatus of more than thirty years in before the Artitometer's commercialization in 1852.

The arithmometer (French: arithmomètre) was the first digital mechanical calculator strong and reliable enough to be used daily in an office environment. This calculator could add and subtract two numbers directly and perform long multiplications and divisions effectively by using a movable accumulator for the result.
