UNIX V4, the first version of UNIX with a C-written kernel, has been successfully recovered from a 1970s tape found at the University of Utah. The recovery was led by Al Kossow and involved reconstructing the data using the readtape program. Users can download the recovered files from the Internet Archive, with guides on running it through emulators like SimH. This marks a significant step in computing history, showcasing UNIX’s evolution from early assembly-coded versions to a more complex system.

The article recounts a two-decade quest to preserve the 1987 Unix game Conquer. The author traced, contacted, and obtained permissions from the original creators and contributors to relicense the code under GPLv3. During this journey, the author modernized the codebase and leveraged contemporary build and packaging tools to make the game easily accessible on modern Linux distributions. The project highlights challenges in archiving software, the importance of clear licensing and documentation, and the community’s role in preservation. Now, both classic and updated versions are available with modern packaging, bridging the past and future for developers.
