Commodore OS
Commodore OS (also known as Commodore OS Vision) is a Linux distribution developed by Commodore USA for PCs, inspired by the legacy of classic machines like the Commodore 64 and the Amiga. It is based on Debian and Linux Mint, combining modern Linux functionality with a heavily customized desktop environment that recreates the look and feel of vintage Commodore systems. Designed primarily for x64 systems, it delivers a nostalgic experience while remaining usable as a contemporary operating system.
Although Commodore OS is not directly compatible with original Commodore 64 software, it includes the free VICE emulator, which supports a range of classic systems such as the Commodore 64, Commodore 128, CBM-II, Commodore PET, Commodore VIC-20, and Commodore Plus/4. The last official release, version 1.0 beta9, was published in July 2012. An unofficial 32-bit version, also based on Linux Mint, exists as well and can run on older PCs with a Pentium 4 or better processor, making the system accessible to a wider range of hardware.
