Debuts Lisa

Apple debuts Lisa, an update to its line of office computers, at its annual meeting in Cupertino, California. The Lisa sports a graphical user interface instead of complex command lines. Instead, users manipulate digital pictures on the screen with a hand-held device called a mouse. The machine has an internal memory of one million characters, about sixteen times than the average currently available personal computer. Two floppy disks are included, and the hard drive can store five million characters. The computer comes with six programs which include a word processor, a spreadsheet program, a graphics program, and an interface that allows users to draw picture freehand on the screen. The machine sells for $9,995.
