Macintosh LC II

Introduced: March 1992
Terminated: March 1993


The upgrade of the Macintosh LC, the LC II, ran a Motorola 68030 processor at speeds of 16MHz.  It was available with hard drives in sizes of between 40 and 80MB.  It had a 1.44MB floppy drive.  The 2MB of RAM were expandable to 10MB.  It had a 256K graphics memory that was upgradeable to 512K.

The Macintosh LC II was also sold as the Performa 400.  When packaged with a built-in modem, software and monitor, it was sold as the Performa 405, 410 or 430 depending on the size of the hard drive. 


Although the Macintosh LC II featured an upgraded processor, it retained the original 16-bit data bus, which limited the speed.  Because of this, the upgraded computer did not run any faster.  However, it still sold well, and though it was short-lived, it spawned a number of subsequent models.
