I was looking at this

http://en.wikipedia.org/wiki/PowerPC_G3

and found this

"The PowerPC 740 is completely pin compatible with the older 603, allowing upgrades to the PowerBook 1400, 2400, and even a prototype PowerBook 500/G3."

So it got me to thinking that MAYBE you could desolder the 603 from a 6500 motherboard and solder a G3 in it's place and MAYBE get a recent version of OS X running on it. I don't have the solder skills or the parts to spare for something so delicate, but maybe someone here does? Does anyone think it's possible?
