What I'm not getting here, is if this machine has officially been declared "dead", by Apple. Some PCs that have been owned by institutions, could very well have copies of Windows installed, as they aren't necessarily OEM copies of Windows in the first place. Philadelphia Community College used to give a course involving the PC, and you got a PC included in the price. (without an OS) I don't think PCC is inclined to rip you off with a computer on which an OS couldn't be installed . So, couldn't you just buy a copy of OS X for it....., or....., have somebody in the know explain why that isn't possible.
As far as this thread goes, it's become a mush-mash of reversals, constantly changing variables. "no money", "it's not mine", I don't want to", et al. At one point, I thought it was cute. At one point, that is.
If you want your car to run, then you need to beg, borrow, buy, or steal the parts necessary for that to happen. Otherwise, it's not going to sit there. All the reasons why not, excuses, or recalcitrance, won't make it happen.
