Many collectors call the Macintosh Color Classic, dating from 1993, their favorite Mac, largely because it signified the merging of two eras. It was the last of the small-footprint compact line, the first with a color screen, and introduced the smiling icon that appears during every Mac start-up. This boxy treasure also featured the first under-the-screen controls for volume and contrast. It still had its imperfections though, such as the combination of a 16 bit data bus and 32 bit processor.
