I have a Amiga 4000T w/a 150mhz Cyberstorm PPC card. I'm in the process of cleaning it up and reinstalling 3.9. I am curious though.. Anyone install OS4 on their PPC based Amiga running at 150mhz? Responsive? What about MOS? How simple is it to install? Can I dual/triple boot? Do I need to buy OS4 and MOS? (Not asking for a pirated copy, just wondering if its free or not)
