commodore - Computer Definition
One of the first personal computer companies. In 1977, Commodore Business Machines, West Chester, PA, introduced the PET computer and launched the personal computer industry along with Apple and Radio Shack. In 1982, it introduced the Commodore 64 (64K RAM) and later the Commodore 128. These were popular home computers, and more than 10 million were sold. In 1985, Commodore's new Amiga series offered advanced imaging and video capabilities at affordable prices. A line of IBM-compatible PCs was also introduced, but the Amiga line was Commodore's mainstay until 1994, when the company filed for bankruptcy. See Amiga and Commodore 64.
