6. The Origin of the Hacker Culture
Note: These comics were written with reference to Eric S. Raymond's "A Brief History of Hackerdom."
Here, "hackers" means people who love exploring computers, building things, and sharing what they learn.
Early Programmers

"In the beginning, there were 'real programmers.'"

"What is a real programmer?"
"Thirty years of training... all in machine code."

"Most came from math, physics, or engineering. They programmed in machine code, assembly, Fortran, and ancient computer languages that are now forgotten."
Early programmers also used many languages that are little known today. Browse this history of programming languages, and you may find a few unfamiliar names.

"Do you know ALGOL or Simula?"
Of course, we must also acknowledge the contributions of women programmers during this period.

"Many early 'real programmers' were women, including Margaret Hamilton and Grace Hopper."
This culture of early programmers helped develop computing and networks. It also contributed to today's hacker and open-source cultures[1].

MIT's PDP-1 and Spacewar!
MIT's early hacker culture had roots in the Tech Model Railroad Club before the PDP-1 arrived. Digital Equipment Corporation introduced the PDP-1 in 1959, and MIT received an early machine in 1961. Students and staff who encountered it created a text editor and a chess program, experimented with computer music, and developed Spacewar! for fun. Spacewar! became one of the earliest and most influential video games.

In the YouTube video below, you can see the music playing and Spacewar! running on PDP-1.
ITS, ARPANET, and a Growing Community
At the time, MIT was becoming a major center of hacker culture through Project MAC's AI group and the later Artificial Intelligence Laboratory. John McCarthy developed Lisp at MIT in 1958. Around 1967, programmers in the AI group began developing ITS (Incompatible Timesharing System) on the PDP-6; development later continued on PDP-10 computers. They shared software free of charge, along with technical ideas, with other universities and research institutions. After MIT's systems joined ARPANET, a precursor to the Internet, these programs and practices spread more easily to connected communities.
