The Macintosh Quadra 605 (also sold as the Macintosh LC 475 and Macintosh Performa 475) is a personal computer designed, manufactured, and sold by Apple Computer from October 1993 to July 1996. The model names reflect a decision made at Apple in 1993 to follow an emerging industry trend of naming product families for their target customers – Quadra for business, LC for education, and Performa for home.[3] Accordingly, the Performa 475 and 476 was sold in department stores and electronics stores such as Circuit City, whereas the Quadra was purchased through an authorized Apple reseller.

When introduced, the Quadra 605 was the least expensive new computer in Apple's lineup. (The Performa 410, introduced at the same time, at the same price of about $1,000 USD, which included a monitor, was based on the much older Macintosh LC II with a 16 MHz 68030 processor.)[3] The Quadra 605 reuses the Macintosh LC III's pizza box form factor with minor modifications.[4]

The Quadra 605 was discontinued in October 1994, and the LC 475 variant continued to be sold to schools until July 1996. Apple offered no direct replacement for these machines, making it the final Macintosh to use the LC's lightweight slim-line form factor. Apple would not release another desktop computer under 10 pounds (4.5 kg) until the Mac Mini, nearly ten years later.
