Apple’s Lisa was the predecessor of the Macintosh that introduced the mouse, the graphical user interface, and the integrated all-in-one design that would characterize the earliest Macs – and later on the iMac.
Introduced on 24 January 1984, the Lisa 2 adopted the same 400 KB 3.5″ floppy drive as the simultaneously introduced Macintosh. It was available with the same 5 MB ProFile hard drive as the original Lisa or an internal 10 MB hard drive.
Introduced in January 1983, Apple’s Lisa shipped that June. The first consumer computer with a WYSIWYG (What You See Is What You Get) display, a GUI (Graphical User Interface), and a mouse, its $10,000 price tag made it anything but successful. Only 11,000 original Lisas were sold.
