It was the first machine to use punch cards to control a sequence of operations. Although it did no computation based on them, it is considered an important step in the history of computing hardware. The ability to change the pattern of the loom's weave by simply changing cards was an important conceptual precursor to the development of computer programming.
The term "Jacquard loom" is a misnomer. It is the "Jacquard head" that adapts to a great many dobbie looms such as the "Dornier" brand that allows the weaving machine to then create the intricate patterns.
