Is a PowerBook Duo 2300c:
It has a German keyboard, and German System 7.5.2 installed but hey, it’s still working after 13 years, and it was well worth the $30. =)
Now if I can only find a way to install an English version of System 7 or Mac OS 8 onto this baby (which doesn’t have a floppy, optical drive or ethernet), then I can even use it for distraction-free writing.
See the Flickr set for more photos, and size comparison with my 12" PowerBook G4.
