You mean an application on AmigaOS act like a minicomputer on its own?
How AmigaOS' architecture and kernel really works. I'm not too familiar with Amiga, so I was curious. Even the previous example quote was a wee bit to understand.
Why being atypical? No huge difference between the kernel and userland? What points are very different from a generic UNIX monolithic kernel?
Thank you. 
AmigaOS is like a microkernel, in as much as everything is modular, sitting on top of a simple memory/process/interrupt management core... but Amiga OS doesn't suffer the performance penalty of other microkernels because it has no security at all.
A microkernel protects the core from all the other parts of the system, so you can in theory replace/upgrade/restart/break any part of the system without taking down the rest of the system, this is the power of a microkernel...
AmigaOS doesn't and thus is atypical (by missing out on this one key advantage of a microkernel, the trade off being that AmigaOS is faster and more memory efficient than regular microkernel) .
