Jasper Found in the Wild: 65nm Xbox 360s are Appearingby Michael Andrawes on November 28, 2008 12:00 AM EST

After entirely too long, Jasper has finally been discovered in the wild. As we originally predicted back in early October, the first Jaspers were identified by being labeled 12.1A on the 12V rail. Somewhat surprisingly, the first ones discovered also came with a 150W PSU. We of course knew this would happen eventually, but many believed that early Jaspers would use left over 175W PSUs. It's still possible there are some Jaspers floating around labeled as 14.2A and including a 175W PSU that were simply never recognized for what they were. Also as predicted, the Jasper motherboard featured a new PSU power connector that prevents using a newer, less powerful power supply on an older Xbox that needs more power. This information wasn't confirmation enough for some, but no doubt remained after one was finally dissected. One other interesting tidbit is the inclusion of 256MB of on-board flash, allowing Microsoft to forgo the memory card for Arcade systems and also to preload NXE without a hard drive.
So far it appears that lot number 0842 from team FDOU or CSON and 0843 FDOU have been confirmed Jasper. Unfortunately, the somewhat confusing bit is that some of these same lot numbers have also been confirmed to be Falcon. Clearly, we are in the midst of a transition period, so there are still no guarantees based on external box markings. If you get a console labeled 12.1A on the 12V rail and comes with a 150W PSU, you can be assured that you have a Jasper-based console.
I would like to reiterate that Microsoft will likely never comment officially on Jasper or any other Xbox 360 revision, so don't waste your time trying to contact them. Along the same lines, your average retail employee is not going to have a clue what you're talking about if you ask, so don't bother.
It may take a few weeks for these to become more common - I still can't find one locally myself, and it would be a total crap shoot ordering online. So the hunt continues around here. We'll have our own dissection and analysis as soon as we can get our hands on one. And if you're hunting for one yourself, post all of your findings in the official thread in the AnandTech Forums.
