EMACS turns 50

Programming used to be a very different experience from the one we know today. In fact, the first programmers didn’t write code at all; the six women who worked on the ENIAC, one of the world’s first computers, at the University of Pennsylvania in 1946 did it by physically configuring switches, cables, and plugboards.

A few years later, MIT engineers programmed the Whirlwind by punching code onto paper tape that was then loaded into the computer’s memory—making it among the first “stored-program” machines. Later, they and others moved on to punch cards, one for each line of code.

By the early 1960s, programmers with interactive computers could use a “line editor” to type their code on teletypes—large, noisy keyboard-and-printer machines. They’d type one line of code at a time, and their work would be saved on a spinning hard disk the size of a modern washing machine.
