Be careful what you believe; some of these stories aren't true or are mis-remembered/reported. An example right at the (current) bottom: As a hardware designer in the late '70s, I can tell you that liquid crystal displays (LCDs) didn't exist as an option when HP started making digital calculators. They went with LEDs because that's what was available at the time for a reasonable cost. ...If there's a back-story wherein HP turned down the opportunity to be the first to use the LCD, it would STILL have to be something more than ten years after they were already making the LED-display calculators...
