That's an odd statement, given that the two world's largest supercomputers are now PowerPC machines, running Red Hat Linux.
But these supercomputers certainly are PowerPC64 machines? I guess I should have written PowerPC (32bit), to be more specific.
If you actually care about the architecture, you might want to have a look at this
PowerPC Notebook crowdfunding campaign.
My niece gave me a mid-2007 MacMini a few months ago I haven't done anything with yet. [...]
I'm more interested in the monitor than I am the Mac, thinker of low thoughts that I am.
But that Mac must be an Intel machine, possibly even a dual-core, then? That would be way faster than my 2005 PowerPC mini (@1,42 GHz). It did successfully install dvdbackup, abcde, lame, flac, and vorbis-tools, though... but compiling G++ 8.2, one of the dependencies / requirements took about 24 hours alone! My /usr/ports partition already is at 9.1G, whereas the rest of the system just uses 1.8G.
Just for fun, and to possibly try FreeBSD on my 1.0 GHz iMac too, I'm also trying to install XFCE now. But that was when I also got my first compilation failure, something to do with Cairo or Mesa... Are you also talking of an iMac, Trihexagonal, or did you mini come with a special monitor?
