Easily the most trivial $1T inventions of all time! Spinning hexagonal mirror, laser, modulated by a serial port running at 14mhz, roughly. A 2 week hardware project and 3 month software project! I am ex Xerox Office Systems Division, 1984, I work at 3406 Hillview Ave, and heard it from work! It created a whole industry of repurposing hardware for new purposes like rockem sockem robots, I did it for our Internet radio service, 1994, at UBC ECE Dept. Just repurposed a portable AM/FM CD player and digitizer board.
