Hint: OS4 is a continuation of the OS commodore shipped with the Amiga, based on the same source code base.
Exactly which AOS source codes were used in OS4? We all know the OS4 kernel is not based on Amiga IP. I seem to remember court docs stating that Hyperion didn't use any of Amiga Inc's IP because it was assembly and was useless. I'm interested to hear exactly what Amiga Inc IP was used in what portion of OS4.
