Jobs worked for Atari and designed video games. He was friends with Woz in college and Woz built blue boxes to make free long distance calls and they both sold them to raise money.<p>Woz worked for HP making calculators and Jobs worked for Atari making video games. Jobs got the idea for Breakout to be the first video game in color, and made a deal with Woz to make the Breakout game for him and share the money.<p>Jobs was always the visionary the one who saw how things should be, Woz was the engineer that made things happen for Jobs.<p>Jobs did the business end of things, marketing, public relations, promotion, giving speeches, while Woz tinkered with stuff and got the stuff to work.<p>The early Apple, the plan was to make a personal computer as cheap as they could with the best quality for that price. Which meant using the MOS 6502 instead of the Motorola 6800 because the 6502 was cheaper. Woz would test the cheaper chips from electronic catalogs to see which ones were best for the money. Woz made the Apple I and it was so cheap at $666.66 that it undercut the other personal computers on the market. Woz later made the Apple II and invented a floppy disk drive for it and Applesoft BASIC and other things.<p>When Jobs started the Lisa and joined the Macintosh project later on, he didn&#x27;t involve Woz and had other engineers and wanted to make the opposite of the Apple II series, a more powerful, expensive computer based on the Motorola 68000 that had a GUI to make it easier to use. The Macintosh project was to be an easy to use $600 8 bit computer, but when Jobs joined it and took over he used things from the Lisa project to make it based on the 68000 instead. It didn&#x27;t sell very well and Jobs got fired in 1985 from Apple.<p>Jobs made his Next company and instead of starting from scratch used Unix instead to base his system on. When Apple bought out Next, and brought Jobs back it merged MacOS with NextOS to make Mac OSX.<p>But in the early Apple the Apple I and II were done by Woz. Without those there would be no Apple and thus no Macintosh and other stuff.
