Thanks Mac, that device does look interesting and would allow me to use exisiting dev tools

shame its 3V but I can maybe live with that. It is more expensive that the AVR too. Think I'll grab one and take a look, thanks!
David, you are correct, my bad. It has been a couple of years since I looked at the QT4 with MON08 vs the BDM system on GB60 etc.
thanks guys.
