If I remember right, there was no software ever made for NT4 PPC. It was always a beta program and never advanced further than that, if I remember right.

No idea about getting an OS on there, but if it's anything like an RS/6000, you're in for quite a trip. Getting the thing to boot of a dang CD is hard enough, but then you have to install and configure it. Belch.
