ArcaOS is an operating system based on the last IBM release for OS/2. While OS/2 barely survives as a legacy system, even after being extended for a while as eComStation, ArcaOS is still being actively developed with Spanish and German language editions expected to be released in the next update.
ArcaOS includes a robust Unix compatibility subsystem, featuring a variety of ported OSS Linux apps and some drivers, but still features the OS/2 Workplace Shell.
ArcaOS is a 32-bit OS that runs on the x86 processor architecture, so should be compatible with some particularly old PCs. Though it's native file system is JFS, it can still work with FAT12, FAT16, or FAT32 formating.
There are two editions available: Personal, which retails for $129 per license, and Commercial, which retails at $229 per license though volume discounts are available. The personal edition includes 6-months support and maintenance, while the commercial edition includes one-year of priority support and maintenance.
