So now I have one sitting in my room.
I also wrote that I would port NetBSD on that machine, I did more research on this subject and it appears that the OpenFirmware is broken on that machines and NetBSD boots from the OpenFirmware so I think that would be near to impossible to do such a port but maybe the sources of the quik bootloader can help.
However I managed to install an old Yellow Dog Linux 2.1 (it was out around 2002) with little tricks.
Finally I inclined to port AROS on that machine, I'm studying slowly how to do it.
The next thing I need to do is to extend the RAM from 32 MB to 128 MB.
The sound made by Bose is absolutely fantastic, It's like you are in a movie theater.
It receives radio (tested) and TV (not yet tested).
See pictures:
