The Apple Lisa is a desktop computer developed by Apple and 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. The development of this computer began in the year 1978, and it underwent many changes during the development period. It was shipped at a high pricing of US$9,995 with a 5 MB hard drive. The high pricing with relatively low performance and unreliable “Twiggy” floppy disks led to poor sales, in which only 100,000 units were sold.
