This is stack of IBM punch cards, also known as Hollerith cards, which were a primary method for data storage and input in early computing and data processing systems.
Here's some information about them:
Function:
They stored digital information using the presence or absence of holes in predefined positions, which were then read by electromechanical machines.
History:
Developed by Herman Hollerith for the 1890 U.S. Census, his innovations laid the foundation for IBM, where the 80-column punch card became an industry standard in 1928.
Significance:
IBM punch cards were crucial for business, scientific, and governmental data processing throughout the 20th century, preceding magnetic storage and influencing lasting conventions like the 80-character line length in computing.
There is over a pound of cards here, though I didn’t count them out.
