On a Dutch blog, you can see a Katz Media Pippin and some of its accessories. Notably, there’s an Ethernet dock and a keyboard.
The Ethernet dock is quite basic and visibly homemade. It resembles the white version seen in Japan.

The keyboard is a black Apple Design Keyboard (like the one from my Power Macintosh 5500) but with a P-ADB connector for the console. It’s a QWERTY variant.
Finally, the 16 MB extension is homemade, unlike mine.
