i have sam460 amigaos cdrom iso as my backup and can test it inside qemu. 
sharing the logs if you needed.

 about real hardware no problem i will ask inside amigan community if someone 
have the opportunity to share the serial debug of sam 460 runinng amigaos.

can i ask you something ?
why you dont try to integrate in qemu the pegasos 2 or the efika machine. i 
have the feeling that probably it can be more simple because more old machine 
and components.
