386BSD

386BSD was a Unix-like operating system, and the first fully operational free and open source Unix built to run on i386 based IBM PC compatible computers. Lynne and William Jolitz began building it in 1989 while at the University of California, Berkeley's Computer Systems Research Group, releasing version 0.0 in March 1992, a more usable version 0.1 in July 1992, and version 1.0 in late 1994. It made Unix available on ordinary, affordable personal computers for the first time and introduced features such as role based security and a modular kernel design. Disagreements between the Jolitzes and the wider user community led to the project splitting into FreeBSD in 1993 and NetBSD, both of which are still active today, while the original 386BSD project itself stopped developing after 1994.
