"The main claim is that it is not a clean room implementation, because those involved have had sight of original Amiga OS code."

a) Fact is that over the half of the original Amiga sources are written in MC680x0 Machine language. Thus quite useless on PowerPC. (This is known fact and even writen in all sorts of Reference Manuals).

b) A lot of parts were Hardware banging things such as accessing the Custom Chips and special Hardware only available in the native Amiga. Thus it's quite useless for PowerPC.

c) Peeking in the internals of Amiga is no secret specially not for an attentive programmer who use to work on that system for many years. Such information goes into blood after a while.

d) Before someone goes to look in the ASM code and then convert any MC680x0 sources to PowerPC ASM source it would be wiser and quite faster and less stress for the programmer to re-code the entire stuff from scratch with modern implementations and interfaces rather than bullshitting on the old sources (in case someone saw them).

e) Re-Using some parts from AROS is no sign of being helpless. It's a sign of being professional and share code with people who already spent a lot of time into solving these problems and AROS obviously benefit from this co-operation. It's professional sign to do code-reuse rather than re-inventing the wheel over and over again.
