After Jobs was fired or quit Apple in 1985 because the Mac was a flop and the Commodore Amiga and Atari ST came out for a lower price with color. Apple had to redesign the Mac and came up with Nubus slots for the Mac II and Mac SE line. They used the 68020 CPU and expandable video cards with up to 16 million colors to rival the Amigas 4086 colors.

IBM countered with VGA and the Adlib and Soundblaster cards came out to have better sound and Windows 3.x sold a lot and Windows 95 basically put competitors to near bankrupt or almost bankrupt status.

Jobs came back and saved Apple using a BSD Unix solution that used the Mac GUI aka OSX.
