Leon,

carefull...
I bought one of those kits hoping to use it, but sadly the IO is limited to
a max frequency of around 3Mhz, even if the internal core is running at
60Mhz, its to do with the way Philips interfaced the ARM core.

Yes, that is annoying. I was puzzled by it when I tried to drive a DAC as 
fast as possible. Philips have an explanation on the LPC2000 Yahoo group; 
IIRC it's nothing to do with them but inherent in the ARM design.
