Seen on Reddit and on eBay, two prototypes of the first PowerBook G3, derived from the PowerBook 3400c.
At the time, when Apple integrated a new processor designed for Mac OS, it did something similar to what it does now: keeping the same machine with a new CPU. But the PowerBook G3 Kanga is unfortunately a rather average machine (unlike the M1) that was not supported under Mac OS X.
The one on Reddit, notably, has Intel flash memory chips for the ROM (I suppose).

A machine in good condition

The second one on eBay is in worse condition.

It’s less clean
