Macintosh LC 520

Introduced: June 1993
Terminated: February 1994


The first of the Macintosh LC 500 line, the LC 520 came in a new all-in-one case that was significantly different from the compact Macintosh line.  It had a 14” RGB display built-in along with a built in microphone and speakers. 

The Motorola 68030 processor ran at 25 MHz.  The hard drive was available with between 80 and 160MB of room.  A 2x CD-ROM drive and 1.44MB floppy drive were standard. 


The new all-in-one Macintosh proved to be a popular home model for Apple.  It had a strange look, resembling a traditional monitor fused with the CPU, however many later models followed in its footsteps. 

The Macintosh LC 520 was also sold as the Performa 520.
