When introduced, the Quadra 605 was the least expensive new computer in Apple's lineup. 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. 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.
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, Inc.
