Lisa II/Macintosh XL

Introduced: January 1984
Terminated: July 1986


The Lisa II offered several upgrades from the original Lisa.  The duel 5.25” drives were replaced by a single 3.5” drive.  It was available with up to 2 MB of RAM and a 10 MB external hard drive.  When the Lisa II was renamed the Macintosh XL in 1986, it included MacWorks.  This emulator allowed the Lisa II to run the new Macintosh operating system.


The release of the much cheaper Macintosh had a significant effect on the Lisa line.  Because of this, Apple halved the price on the Lisa II.  Purchasers of the original Lisa had a window of time for a free upgrade after which they had to pay an upgrade fee.  The name change was undoubtedly based on the success of the Macintosh line; however, it was still too expensive to become a widely adopted computer.
