Final answer:
The Tech Model Railroad Club (TMRC) shared their code openly, which is something modern-day video game makers would find surprising and ill-advised.
Step-by-step explanation:
The Tech Model Railroad Club (TMRC) did something that modern-day video game makers would most likely find surprising and ill-advised, which is a. They shared their code openly.
The TMRC was a group of students at the Massachusetts Institute of Technology (MIT) who were passionate about model railroads and computers. Back in the 1960s, when computers were not as widely available as they are today, the club members wrote software to control their model railroad layout. Rather than keeping their code proprietary like video game makers do today, they openly shared their code with others in the computing community.
This kind of openness and collaboration was common among early computer enthusiasts. They believed in the free exchange of knowledge and wanted to inspire others to learn and improve upon their ideas. Today, video game makers tend to keep their code secret as a way to protect their intellectual property and maintain a competitive edge in the market.
