But, speaking as the author, PowerPC BeOS is criminally unloved.
The pivot to x86 was IIRC initially actually met with some trepidation, given not just the big changes in architecture but the incredibly broad and messy world of x86-compatible proprietary hardware – a problem, as it turns out, that neither Be nor its ecosystem were ever really able to master.
Nowadays, though, and no offense to the OP, no one remembers where BeOS got its legs. And this has translated into what's been preserved. You can find some Intel BeOS stuff in some corners but almost no PowerPC.
