I'm still trying to fluff out and even if I don't  
describe half the Linux architectures I interrogated git to get a list  
of when each one was added. Might be useful.

Half the game consoles out there are Power. (Dunno about the current  
generation.) Back when Praystation 3 supported Linux built-in, it was  
the cheapest way to get a 64 bit PPC system with the Cell processor  
stuff. (Which alas never took off because it was way too hard to  
program and they were just proprietary enough in the programming info  
to prevent open source people from ever quite managing to care. These  
days Hexagon has all the "3D rendering in software" buzz they used to  
brag about, but that's problematic to get a test environment working
