...because Phase 5 done some PPC accelerators for A4000 and A1200, and people started the MorphOS project on them.
But at that time, thinking to go elsewhere (X86?) would raise very strong angst (just imagine! :-O )

1995 is when AROS was started so there was already a start for x86 Amiga-like OS the same time the ill fated PPC was announced by AT/EScom. Then AI announced the next generation Amiga OS, DE, would be primarily targeting x86 and even had a low end K6-2 Dev machine being sold.
