Thanks -- though poking around, it seems I'm not the only one who made this mistake. I did see the note about nrfgo being needed, and poked around for about 20 minutes trying to figure out what was meant by that, and eventually arriving at the wrong conclusion. In any case, how "highlighted" the need was is mooted now, with the new dev kits.

It was pretty clear the old dev kit needed Nordic's standard base kit to make it work. Nordic certainly highlighted it on the site at the time. It made sense then as all their dev modules plugged into it, of course the most recent kits don't even need that any more.

You have a couple of options over and above building your own complete nrf51822 board. One is just to power up the board you have, there's a few questions here about how to do that. Another is to buy one of the relatively cheap 3rd party mounting boards which has switches and leds on it. mommosoft makes one which has a USB/UART connection, 8 switches, 8 LEDs, power and some breakout connectors, there are probably others, price not radically different from that Segger cable and no messing about. Or you can build your own one of those if you just want power and LEDs, the connectors on the DK are standard, and plug the board into it.

Adafruit also sell a 'JTAG (2x10 2.54mm) to SWD (2x5 1.27mm) Cable Adapter Board', which can be used to break out a 1.27mm spaced 2x5 cable to a larger 2.54mm spaced connector (though you will also need a 1.27mm pitch cable with all 10 holes present to plug into it (such as this).

Thanks. I imagine it's this one: www.segger.com/jlink-adapters-9pin-cortexm.html

Well, you can get the adapter directly from segger. They sell them for their JLink line. If you want to get started with Eclipse, this blog site would be a good start. It has example code with a one to one iOS code to help you going. http://embeddedsoftdev.blogspot.ca/p/ehal-nrf51.html. I hope you like it.
