The Macintosh LC (meaning low-cost color) is Apple Computer's product family of low-end consumer Macintosh personal computers in the early 1990s. The original Macintosh LC was released in October 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.
