At the time, the MIT Artificial Intelligence Lab was the birthplace of hacker culture. In the late 1960s, they developed a time-sharing operating system called  ITS(Incompatible Timesharing System)that ran on PDP-10 and a language called LISP, which was made available free of charge to other universities and corporations. After the early form of the Internet, the ARPAnet, was connected, the hacker culture spread to other universities and institutions along with ITS.

The PDP models made by DEC contributed greatly to the hacker culture and the birth of free software. It was a kind of mini computer that was sold at a relatively low price and was particularly popular in universities. For reference, DEC donated a PDP-1 to MIT in 1961[2].
