That is mostly correct. In order for Windows to run on a PPC computer, Microsoft would have to recompile all of their software on a PPC processor, which is a large task. As you may know, processors only understand 1s & 0s, how the processor interprets the 1s & 0s is up to the designer of the chip. This is why Rosetta is needed to translate PPC instructions into an understandable form for Intel processors to run native PPC code.
Basically that there has only been one version of Windows to run on PowerPC machines and that was in the mid to late 1990s. If Microsoft had wanted to run Windows on another processor, they could do it, but it wasn't worth the money to them.
Add to that the fact that 3rd party developers would also have to develop software for the platform and you end up with a situation where Mac OS X users are now--waiting for native software.
The last version of Windows for PowerPC that Microsoft released was Windows NT 4.0 (and as I recall they stopped supporting that around service pack 4). Further, there wasn't much software for it and Apple never made systems that it could run on.
So if you can find an old non-Apple PowerPC system (they are on ebay from time to time) and don't mind having almost no software, and using a 1996 version of Windows and Internet Explorer... well, then there is nothing stopping you.
I think I saw an IBM workstation that went for under $150... I believe that system had a PowerPC 604e at 200 MHz. Windows NT 4.0 should work on that one. And would be a lot faster than any PCs of that era... though without a lot of software it would be hard to tell.
I don't think he's really asking, he's just raising his post count. What kind of question is that, anyway. Nobody, who has the skills to find, register at, and post at a Macintosh community forum, is that clueless. Especially by their 350 something-th post. Also, take a look at another thread he started here.
