FWIW iBook G3 is circa 2003-2006 so only 20-23 years old. Not 27.
Way to make me feel older than I already do lol.
We used these in when I was in high school, they'd wheel in a cart full of them into the classroom, and had a Wireless B Airport on the cart they'd plug in to the Ethernet on the wall.
Literally my first experience with WiFi
