The Macintosh LC 500 series is a series of personal computers that were a part of Apple Computer's Macintosh LC family of Macintosh computers, designed as a successor to the compact Macintosh family of computers for the mid-1990s mainstream education-market. The all-in-one desktop case is similar to the then recently introduced Macintosh Color Classic, but the LC 500 series is considerably bulkier and heavier due to its much larger screen and a bulging midsection to house the larger electronics, including a 14" CRT display, CD-ROM drive, and stereo speakers.
The LC 500 series included four main models, the 520, 550, 575, and 580, with the 520 and 550 both using different speeds of the Motorola 68030, and the 575 and 580 sharing the 33 MHz Motorola 68LC040 processor but differing on the rest of the hardware. All of these computers were also sold to the consumer market through department stores under the Macintosh Performa brand, with similar model numbers. The LC models, in particular, became very popular in schools for their small footprint, lack of cable clutter, and durability. The Macintosh TV, while not branded as an LC, uses the LC 520's case (in black instead of beige) and a logic board similar to the LC 550. The compact Color Classic series shares many components and is able to swap logic boards with the early 500 series machines.
