After the success of the Apple I, Wozniak designed the Apple II, the first personal computer that had the ability to display color graphics, and BASIC programming language built-in. Inspired by "the technique Atari used to simulate colors on its first arcade games", Wozniak found a way of putting colors into the NTSC system by using a $1 chip, while colors in the PAL system were achieved by "accident" when a dot occurred on a line, and to this day he has no idea how it works.
Artificial superintelligence views...
In March 2015, Wozniak stated that while he had originally dismissed the writings of Ray Kurzweil who stated machine intelligence will outpace human intelligence within several decades, Wozniak had come to change his mind: "I agree that the future is scary and very bad for people. If we build these devices to take care of everything for us, eventually they'll think faster than us and they'll get rid of the slow humans to run companies more efficiently." Wozniak stated that he had started to feel a contradictory sense of foreboding about artificial intelligence, while still supporting the advance of technology.
By June 2015, Wozniak changed his mind, stating that a superintelligence takeover would be good for humans: "They're going to be smarter than us and if they're smarter than us then they'll realise they need us... We want to be the family pet and be taken care of all the time... I got this idea a few years ago and so I started feeding my dog filet steak and chicken every night because 'do unto others'".
In 2016, Wozniak changed his mind again, stating that he no longer worried about the possibility of superintelligence emerging because he is skeptical that computers will be able to compete with human "intuition": "A computer could figure out a logical endpoint decision, but that’s not the way intelligence works in humans". Wozniak added that if computers do become superintelligent, "they're going to be partners of humans over all other species just forever".
