In the late 1950s, a group of MIT students obsessed with model trains gained access to a computer they could operate themselves. They were less interested in what the machine was supposed to do than in discovering what it could do.Decades later, their experiments would become part of the story of programming culture. In his 1984 book Hackers: Heroes of the Computer Revolution, journalist Steven Levy traced the people, ideas and unwritten rules that shaped the early hacker community and influenced the culture around free and open software.
It started with a model railroad club
The story begins with MIT’s Tech Model Railroad Club. Some members were fascinated by the complex electrical systems beneath the miniature trains, including switches, relays and control circuits.The club used the word “hack” for an ingenious solution or modification created for the satisfaction of solving a problem.When MIT’s TX-0 computer became available, some of these students found something that was very different from the traditional computing experience. Instead of submitting punched cards to an operator and waiting for results, they could interact directly with the machine.The computer became a place for experimentation.Students began spending long hours working on programs, sometimes using late-night access when the machine was less busy. The emphasis was on exploring, improving and understanding technology.
The principles that became the hacker ethic
Levy later described several principles that characterised this early hacker culture.Among them was the belief that people should have access to computers and information, that systems should be understood by taking them apart, and that people should be judged by what they created rather than by their age, academic background or social position.One example was Peter Deutsch, who began interacting with MIT’s hackers while still very young. His ability to program earned him acceptance among much older students.The idea was simple: ability mattered more than credentials.
Spacewar and the idea of sharing code
The culture also produced Spacewar!, created in the early 1960s by a group of MIT programmers including Steve Russell and others.The game featured spaceships battling around a star and became one of the landmark early computer games. Rather than being treated purely as a commercial product, the program circulated among computer users and was modified and improved by others.The model was fundamentally different from today’s conventional software business. Code could be examined, changed and shared.The term “open source” would not be coined until decades later, but the practice of collaborative software development had already appeared in early computing communities.
From MIT hackers to Silicon Valley
Levy’s story eventually moves beyond MIT to the growing community of computer enthusiasts in California.Hobbyists gathered to exchange hardware designs and ideas, creating communities in which people shared technical knowledge. Among those involved was a young Steve Wozniak, who later co-founded Apple.But another view of software was emerging.In 1976, Bill Gates wrote his famous “Open Letter to Hobbyists”, objecting to the widespread copying of commercial software without payment. Gates argued that software development required investment and that unauthorised copying reduced the incentive to create software.The disagreement captured a conflict that would continue for decades: whether software should primarily be treated as a commercial product or as knowledge that users should be free to study, modify and share.
The programmer who refused to let the culture disappear
Levy’s book eventually turns to Richard Stallman, an MIT hacker who became increasingly concerned about the restrictions placed on software.Stallman went on to launch the GNU Project in 1983, with the goal of creating a free Unix-like operating system. His work helped establish the free software movement and eventually became part of the broader history surrounding Linux and modern open-source development.Today, collaborative software development is central to the technology industry. Developers routinely share code, report bugs, modify projects and contribute improvements through platforms such as GitHub.The technology has changed dramatically since the days of the TX-0. The basic instinct described by Levy, however, remains familiar: understand how something works, experiment with it, improve it and share what you learn.That culture began long before “open source” became a familiar term. At MIT, it started with students who simply wanted to find out what the machine could do.Disclaimer: This article is based on publicly available information and accounts of early computing history, including Steven Levy’s Hackers.
