Original Apple, fully tested and deep cleaned, "Bondi" blue M4848 (hockey puck) USB mouse that shipped with the first 1998 iMac G3 model.
The Bondi blue mouse is a slightly different colour to the later blueberry versions although it can be hard to tell unless you put them next to each other. Most mice sold as being "Bondi" and actually the later, much more common Blueberry version. Bondi mice serial numbers typically end in "DL0" and they came with a blue and white rubber ball rather than the grey and white used in all subsequent variations. It does not have the indentation in the button that Apple added later to help prevent the mouse rotating during use. Although the PCB is functionally interchangeable with the revision 2 board used in the slot loading iMac G3s, this revision 1 board is green on both sides which affects the appearance of the mouse from above.
It has a 60cm cable and one button but it will function on any computer with USB.
We completely disassemble and clean them inside and out. All hockey puck mice originally had a matt coating applied to the coloured inserts but over time this gets very tacky and dirty, and eventually rubs off. Although we still clean this off, the Bondi version retains a matt finish unlike all later versions that become shiny.
