I got this working a few years ago on era-appropriate hardware. It was awful -- unstable and crashy. There were glimpses of what they were trying for, but it was painfully obvious they were a long way from even the stability of 7.5. I'm sure it was a tough call, but whoever decided to axe it made the right one. Besides, if it had succeeded, they might not have bought NeXT and we might not have gotten OS X!
