Dennis Koble: APX Avalanche, Imagic   Dennis Koble was an early Atari employee, where we would become manager of the computer and consumer divisions. He designed Atari's "Touch Me" handheld electronic game. He also wrote three programs that were published by Atari Program Exchange: Avalanche, an adaption of the coin-op game which he also created; and the text adventure games Chinese Puzzle and Sultan's Palace.    He was at Atari for about 4 1/2 years before leaving to co-found the video game publisher Imagic. There, he was perhaps best known for creating "Atlantis" for the Atari 2600 (which we don't actually talk about in this interview.)   This interview took place on May 15, 2018. A video version of this interview is available.   "We had to show our best stuff. And we wanted to show technological tricks that we figured the Activision guys hadn't seen before. I don't know if they felt that rivalry toward us at that point, but it became a rivalry a little later, it really did."    Video version of this interview   AtariMania's list of Dennis' games   2017 ataricompendium.com interview with Dennis   Dale Yocum interview   Lee Actor interview   Bob Smith interview   Rawson Stovall interview
