muLinux was an Italian, English-language lightweight Linux distribution maintained by mathematics and physics professor Michele Andreoli, meant to allow very old and obsolete computers ( 80386, 80486 and Pentium Pro hardware (dating from 1986 through 1998) to be used as basic intranet/Internet servers or text-based workstations with a UNIX- like operating system. It was also designed for quickly turning any 80386 or later computer into a temporary, powerful Linux machine, along with system repair, education, forensic analysis and what the developer called proselytizing. In 2004 reviewer Paul Zimmer wrote, "Although there are several other single-floppy Linux distributions, none can match muLinux's extensive and unique combination of useful features." The last version update was in 2004, when further development of this " linux-on-a-floppy" distribution ended.
