While the Apple I computer was effectively created and sold for the first time in 1976, Lisa remains one of Apple's most famous early computer systems. The system was created with inspiration from the Xerox PARC Alto and featured Apple's first graphical user interface with Windows and icons. Apple also included its one-button mouse. Lisa integrated a 5 MHz Motorola 68000 processor, 1 MB of RAM, as well as a 871 kB 5.25-inch floppy drive. Lisa, which is believed to have been named after Steve Jobs' eldest daughter, Lisa Nicole, was released in 1983 and discontinued in 1986. Due to the computer's high price of $9,995, it did not sell in high volumes, and had to make way to the Macintosh, which launched in 1984 and laid the foundation or today's product line that include in the iMac and Mac Pro - even if the hardware and software architecture has changed significantly over the years.
