True. I do not know what hosting platform the other person is using. 
He has bought one of my little JTAG-ICE units, though, and we may 
hear from him how he gets on with it.

That's good to know. I assume you have a genuine ($300) Atmel JTAG 
ICE since you mention it on your Web site.

I don't know how people work without an in-circuit debugger. Many 
problems posted here and on other groups could be solved by the 
poster if they had an OCD/ICE. I think it is a failing of Atmel that 
they keep changing the debug interface and the ICE adapters are so 
costly. After a really bad experience with the original Z8 Encore! I 
must say I hate ZiLOG, but their one-wire debug interface is great. I 
make an adapter for that, too, and it's only $8.50. I think people 
starting projects should consider the ATmega series with JTAG 
interfaces so that they can use an in-circuit debugger, either with 
my adapter or one of the other JTAG ICE clones.
