Check this great story out.
YAMHILL, Ore.--There is a story behind every electronic gadget sold on the QVC shopping channel. This one leads to a ramshackle farmhouse in rural Oregon, which is the home and circuit design lab of Jeri Ellsworth, a 30-year-old high school dropout and self-taught computer chip designer.
Ellsworth has squeezed the entire circuitry of a two-decade-old Commodore 64 home computer onto a single chip, which she has tucked neatly into a joystick that connects by a cable to a TV set. Called the Commodore 64--the same as the computer system--her device can run 30 video games, mostly sports, racing and puzzles games from the early 1980s, all without the hassle of changing game cartridges.
