Seen on eBay, a prototype of the PowerBook G3 Kanga. This type of PowerBook G3 is a bit special: it adopts the design and motherboard of the PowerBook 3400c with simply (or almost) a faster CPU. This choice makes it officially incompatible with Mac OS X.
What’s quite strange is that the seller initially listed this model with photos of the Mac powered on (you can see the smiling Finder) in an earlier listing before relisting it without those images.
In the second listing, we have the same Mac… but without the screen (and as a direct purchase). You can also see that the Caps Lock
key is stuck, by the way.
