After the original iMac which was available only in “Bondi” blue, a second and third generation of CRT iMac using the same basic design became available in five colors. While the original Bondi blue Mac was a greenish blue and named after a popular Australian surfing beach, the second and third generation were named for fruit colors: lime, strawberry, blueberry, grape, and tangerine. Although the colors were named for fruits, the shades were arguably unfruitlike. Like the original iMac, the case was translucent, rather than completely transparent.
This blueberry iMac example is a G3/333MHz model very similar to the 266 MHz “Revision B” iMac that preceded it in the same year (1999). This iMac G3/333 had a larger hard drive and lacked the “Mezzanine” port.
Also note that this iteration of iMac included a matching Apple USB Keyboard (M2452) and Apple USB Mouse (M4848). The mouse was often criticized for its circular, “hockey puck” shape with critics claiming it was difficult to locate the top button since the shape was a circle. In this revision, Apple added a dimple to the top of the mouse to help address this issue.
