EmuTOS: a Free operating system for Atari computers

EmuTOS is designed to run on traditional Atari hardware (ST, TT, Falcon, based on Motorola 68000  or ColdFire microprocessors) and their emulators. It features functionality similar to TOS, which powered the Atari ST and its successors between 1985 and 1994. EmuTOS can run on real hardware, either as ROM replacement or from floppy, or on any Atari emulator such as ARAnyM, Hatari, or Steem SSE. EmuTOS is Free Software, and can run legacy third-party software on emulators without requiring copyrighted Atari ROMs, thereby avoiding legal issues.
