Apple's Lisa was the first computer to use a Graphical User Interface (GUI). Incorporating the powerful Motorola 68000 procesor, and a mouse and pull-down menus, Lisa was intended by Apple's founder, Steve Jobs, to set the technological standard and become the market leader in personal computers. Unfortunately, at just under $10,000 when launched in 1983, the price was too high for most potential buyers, but the innovations of the Lisa led directly to Apple's succesful Macintosh.
