BTW, this was called the Jacquard Loom, named after the inventor,

designs for his difference engine.
And Hollerith's card were directly copied for use as punch cards for
computers. The standard 80 column card is exactly the same size as those
used by Hollerith, although Hollerith's cards used fewer holes.
And after a couple of mergers, the Hollerith Tabulating Machine Company
_is_ IBM.

Of course, the main reason they cuddle up is to screw somebody else.

it did take a program for input, process it, and
output it in the form of
fabric. (I think this was right before CGA was made a standard...)
I remember seeing a picture of this machine-- it was a link-belt of
cards in a loop, with holes punched through them. They would pass by
this 'reader' thingie which would 'read' the card with a matrix of
metal rods poking through the holes.
