Third-party operating systems that replaced the manufacturer's system:

    Would you count ZCPR{,2,3} on CP/M systems?
       ...  Xenix/Double-DOS/etc. on MS-DOS systems?
    Amdahl's Unix(TM) is by some accounts the best way to get Unix
                on IBM 370-family systems.
    GE's CTSS runs on the Honeywell DPS-8.
    Pick, OS-9, Unix, Minix, etc. typically replace some other os.
    David Beckemeyer's micro-RTX replaces the Atari-ST's GEMDOS.
