Apple Computer's business division was focused on the Apple III, another iteration of the text-based computer. Simultaneously the Lisa group worked on a new machine that would feature a completely different interface and introduce the words "mouse", "icon", and "desktop" into the lexicon of the computing public. In return for the right to buy US$1,000,000 of pre-IPO stock, Xerox granted Apple Computer three days access to the PARC facilities. After visiting PARC, they came away with new ideas that would complete the foundation for Apple Computer's first GUI computer, the Apple Lisa.
