Jeff Lee was Gottlieb's video game artist. He told us that Caveman was his first project there. He also told us that Joel Krieger did most of the video programming for Caveman but Joel left the company before the game was released so Frank Starshak finished off the video programming. John Buras told us he programmed the pinball portion for this game. An earlier pinball machine that used a video screen to display player scores is Universal Kabushikigaisha's 1979 'Harem Cat'.
