The Macintosh LC (meaning low-cost color) was Apple Computer's product family of low-end consumer Macintosh personal computers in the early 1990s. The original Macintosh LC was released in 1990 and was the first affordable color-capable Macintosh. Due to its affordability and Apple II compatibility the LC was adopted primarily in the education and home markets. Together with the Mac IIsi, it introduced built-in audio input on the Mac. The "LC" name was subsequently used for a line of low-end Macintosh computers for several years and spanned the 68k to PowerPC transition.
Macintosh computers, especially the color Macs starting with the Macintosh II in 1987, had always been rather expensive computers with large profit margins. The original LC was an attempt at an affordable, modular, color-capable Macintosh. Compared with earlier Macs, Apple cut some corners on performance and features in order to keep the price down.
The Mac LC sold well, and in 1991 was replaced by the LC II, which replaced the LC's 68020 processor with a 68030.
