It was bundled with two useful programs designed to show off its interface: MacWrite and MacPaint. On January 24, 1984, the Macintosh was released for a retail price of $2,495.00. Jobs' leadership at Apple ended in 1985 when there was an internal power struggle with Apple's CEO John Sculley. After his visit to Xerox, Jobs hired Harmut Esslinger to work on the Macintosh line. Jobs, hearing about a new graphics user interface being developed at Xerox, traded Apple stock options to see the GUI. Raskin left in 1981 due to personality differences with Jobs. Jobs realized the Macintosh was more marketable than Lisa so he focused his attentions on the new system. This design caught the eye of Steve Jobs, the co-founder of Apple. The final Mac design was self-contained and had a non-expandable 128 kilobyts of RAM. This design used few RAM chips than Lisa, the other computer that was being developed by Apple, and was mych cheaper. By December 1980, Smith was able to design a board that utilized 68000 and had the capacity to support a 384x256 bitmap display. Smith built the first Macintosh board according to Raskin's specifications: 64K of RAM, Motorola 6809E microprocessor, and had the ability to support a 256x256 B&W white bitmap display.
