Is the original project source available?
last time I checked: -
no -
and I am afraid it's still -
no -
you can contact the ex-NATAMI team (Apollo-team)
and ask them for their sources
they might agree IF you have a valid purpose
e.g. because you are willing to develop a new-amiga platform
or to improve/test their core
or something similar
but keep in mind their code is NOT opensource
don't ask me why, I am not affiliated with them
I had a few interests in supporting 68K
so I started to check around, meeting their project
currently I am definitively not interested in 68k
since I am busy with my own toy-RISC project
