The Centris -> Quadra transition was a similar computer, but not the same. For example, the Centris 610 was a 20 MHz 68LC040 and the Quadra 610 released shortly thereafter was a 25MHz 68040 (some shipped with a 25MHz 68LC040, though).
So right. I think I was thinking of the Performa sub-brand.
The Macintosh Performa is a family of personal computers designed, manufactured and sold by Apple Computer, Inc. from 1992 to 1997. The Performa brand re-used models from Apple's Quadra, Centris, LC, Classic, and Power Macintosh families with model numbers that denoted included software packages or hard drive sizes. Whereas non-Performa Macintosh computers were sold by Apple Authorized Resellers, the Performa was sold through big-box stores and mass-market retailers such as Good Guys, Circuit City, and Sears.
