ttylinux
TTYLinux is a tiny Linux distribution designed to run on multiple CPU architectures, focusing entirely on a command-line environment. It is extremely lightweight, with minimum requirements of just 8 MB of free disk space, an i486 CPU, and 28 MB of RAM, making it suitable for very old or resource-constrained systems. Despite its small size, TTYLinux provides a complete command-line environment ready for networking and Internet access.
The last official release, version 2015.02, was published in February 2015 and received an update in March 2015. Its minimal design and portability make TTYLinux ideal for advanced users who need a compact, efficient Linux base for servers, embedded systems, or custom lightweight installations.
