Can anyone point me to a development board that has the 6 pin ICE connector and pinouts for the dip 328P and a socket for the chip?  I've got the Xplained version but I would also like a socket version of it.  I've tried using the Uno but having a difficult time getting it to work with Studio and the ICE debugger. 

This topic has a solution.

Edit
I should ask....what are you having trouble with? The ICE should connect right to it and work but you need to disconnect the reset line from the on board programmer. It's a little jumper you cut.

To use the debugger, you need to open this jumper, to use the USB to load sketches, make this jumper (add a solder bridge).

 

 

 

 

Not sure why this displays double???

I don't understand  that solder bridge? Surely my added '3', '4' route already joins the thing that 1 / 2 will join when the bridge is made?

It does join 1/2, but to use the debugger you cut that link(3/4), then to restore normal operation after a debug session you bridge the 1/2 with solder.

Ah, I don't think that point was clear from your post. So OPs initial action is to actually break 3/4 and then, later, when all the debugging is done and he wants to restore bootloader operation he makes the 1/2 solder bridge? (obviously first using the debugger to actually program the bootloader into the AVR and set the right fuses!)

Just want to clarify something regarding the jumper you need to cut.  Its located between the two pads(1 and 2) on the PCB.  You simply use a sharp knife to break the trace.

So in effect the schematic is wrong and it really should have been:

Yes, your diagram is more intuitive. The original schematic is "accurate" in that it shows the default delivered state of the Uno pcb.
.
I suspect that the original schematic is the best way to represent a "n/c" solder bridge.
