<P> The Apple Lisa is a desktop computer developed by Apple , released on January 19 , 1983 . It was one of the first personal computers to offer a graphical user interface ( GUI ) in a machine aimed at individual business users . Development of the Lisa began in 1978 , and it underwent many changes during the development period before shipping at the very high price of US $9,995 with a 5 MB hard drive . The high price , relatively low performance and unreliable Apple FileWare , or `` Twiggy '' floppy disks , led to poor sales , with only 100,000 units sold . However , these sales generated about $1 bn in revenue , which would later help keep the company afloat amidst an ongoing crisis . </P>
