*** If this is in the incorrect category can a moderator please remove it as appropriate ***

Does anybody have an unwanted GuruPlug JTAG module? I would like to make use of one to flash my GuruPlug Plus but I am disheartened to see that this costs over 30... I understand it's a slim chance but I was wondering perhaps if anybody has one they no longer require?

Thank You.

Heya, figured I'd bump this rather than starting a new thread (hoping you found a solution to your search). I'm looking to buy a JTAG interface that will be compatible with the plug computers pin headers. I've looked at quite a few USB JTAG interfaces and have yet to find one with a matching connector. Has anyone successfully used a non sheeva module on their plug?

The OLPC XO Serial Adapter Kit $25
works on my DreamPlug at half the price.
The only proviso is that you must connect Black, Red, Green to Ground, Rx, Tx (respectively) rather than the way you would if you were connecting to an XO.
No soldering involved.  It comes with the correct connector.
It's very small and much more convenient than the expensive one provided by Globalscale.

You could also consider Adafruit's FTDI Friend:

but you'd have to also get the correct connector- one of the "picoblade" products from AMP.   
Available here:

But you'd have to figure out how to connect the wires- I haven't figured it out yet although haven't tried very hard because the XO adapter works very well.
