TLDR on the history side of the article

In 1804, a French weaver named Joseph-Marie Jacquard patented a loom that could weave intricate patterns using punch cards — paper cards with encoded holes.

Once they pass through the loom, the presence or absence of a hole tells the loom which warp thread to raise or lower, acting as the earliest form of binary code programming. Weaving that once required a master weaver and an assistant could now be done by craft hobbyists.

And based on this card, IBM and others developed the 40 / 80 character punch cards which are the reason SAP IS STILL ONLY SUPPORTING 40 CHARACTERS PER FIELD
