- This is very interesting. Is this the only translator you know of, or are
- there other examples. I can imagine that both AT and Apple would be very
- interested in this. Any indications on how much faster this kind of
- translation would be when you compare it to the `hardware emulation' of
- 680x0 code that's built into the PPC?
