David Thornburg, Koalapad inventor   David Thornburg invented the KoalaPad, a touch tablet that was available for the Atari 8-bit computers, Commodore 64, Apple II, and the IBM PC. A version for the TRS-80 Color Computer was also available, sold as the TRS-80 Touch Pad. He is also the author of The KoalaPad Book, which was published in 1984.   This interview took place on May 22, 2017. In it, we discuss George White, the founder of Koala Technologies, whom I previously interviewed.   Teaser quote: "You know how to take things apart. Good for you. But you've never built anything in your entire life. You have no idea what it's like to invent something that has generated livelihood for hundreds of people, and is making a difference in the lives of thousands of people."   Video version of this interview   George White interview (audio)   George White interview (video)
