Hi,

I saw this too, it's quite interesting.

Since the motorola's US patent is available since some time, I think 
most of the timings used in WinUae "cycle exact mode" are already 
correct and similar to this doc, or tested against real hardware.

In the case of the old UAE cpu used in STF/STE emulation for timing 
critical operations (raster, fullscreen, ...), it could be useful to add 
some special cases (prefetch behaviour are sometimes a cause for some 
failing games protection in Hatari).
