Legacy OS (formerly TEENpup Linux) is a distribution based on Puppy Linux. Although the original concept was to create a flavour of Puppy Linux with more applications and a more appealing desktop aimed at teenage users, Legacy OS has now grown to become a general purpose distribution. It comes with a large number of applications, browser plugins and media codecs as standard software. Despite these enhancements Legacy OS is still perfectly suitable for installation on older and low-resource computers, as well as modern hardware.
