In reply to Comment 12 (porneL):
> There is supposed to be JIT emulation there!

Yes, but it isn't integrated yet. Everything on the show still ran on the interpreter. And that reaches about 040/33 speed (roughly). I think the show version still had the 68k font code, too. The Antialiasing is really slow on the emulation. Our latest stuff has this already ported to PPC and is much faster.

> there still is enough of 68k code to have impact on system (why aren't they using+testing PPC code? It was said that its a matter of one compiler switch...)

What you see is mostly graphics and intuition. Yes, this has an impact on speed. We do have a ppc-native intuition in the meantime but it wasn't on the show.

The library system has changed. It's quite easy to compile code for PPC but some changes are still required to adapt the code from the old library model to the new one. It's not dramatic, but it is mostly grunt work.

For applications, this is a lot easier. Most applications do compile without changing the source code. But for libraries there's some work to be done, and that simply takes a few days.

However, conversion is progressing nicely.
