History: Named for one of its designer's daughters, the Lisa was supposed to be the Next Big Thing. It was the first personal computer to use a Graphical User Interface. Aimed mainly at large businesses, Apple said the Lisa would increase productivity by making computers easier to work with. At $9,995 U.S. it was a plunge few businesses were willing to take. When the Macintosh came out in 1984 for significantly less money, it eroded the Lisa's credibility further. In January 1985, the Lisa was renamed the Macintosh XL, and outfitted with MacWorks, an emulator that allowed the Lisa to run the Mac OS. The XL was discontinued later that year.
