    One of Microware System Corp.'s first products was a minitasking ROM (RT68MX) that would work with a Motorola Evaluation Kit or an SwTPC
    6800 microcomputer. I remember it was 1 or 2K bytes, and you had to
    set up the task table by hand, but it would multitask. They also sold
    an integer BASIC compiler (A/BASIC) that would produce programs
    compatible with the RT68MX ROM. It was entertaining to try to compile
    a BASIC program using an SWTPC 300 bps cassette tape interface.
    Microware later produced OS-9, which actually is a useful product.

    And when Apple introduce Mac/OS9 (which just says "OS9" on the box), they were sued because of trademark infringement by whoever owns OS-9 now.
    Some of the people who have Radio Shack Color Computers still run OS-9
    on them. And I believe there is a version of OS-9 (the Microware one) available for 68000 processors.
