All of the old documents say that BeOS doesn't support powermac 7200's out of teh box, but what if I have a G3/G4 sonnet card in it? Will BeOS then support it? Or will I have to wait for haiku to be ported to it?
Here is list of compatible powerpc systems for BeOS.
Check it for more information to get you started.
For Haiku, it'll be awhile before it comes to powerpc - long wait.
Is there anyone who is currently working on the Haiku PowerPC port? Can anyone give a report on the current state?
