The Lisa was built by Apple Computer and development originally began in the late 1970s. It was their first attempt at designing a personal computer with a graphical user interface. First introduced in January 1983, it was the first PC with a GUI and mouse. It used a 5mhz Motorola chip, 1MB RAM and sported two 5.25 inch floppy drives. The operating system had memory management and was capable of multitasking.
The machine turned out to be a complete failure for Apple, however. The high price tag had consumers balking, who prefered the more cost effective IBM PC instead. The $9,995 price was mostly due to the whopping 96kb of RAM the system used. At the time, it was an extravagant amount of memory. The introduction of the similar but less expensive Macintosh also wound up pre-empting the Lisa, which saw two later models before being discontinued in 1986.
