Lpc2000

A client of mine who's been using the Nohau board for software
development zapped the JTAG inputs to the LPC2106 by connecting the
adaptor while the board was powered up - something to watch out for. I
replaced the LPC2106 with an LPC2104 (all I've got here) and got it
working again.

I suppose the safest thing to do is to power up the target board,
unplug the USB, connect the JTAG and plug it into the USB port on the PC.
