AnandTech's in depth look at the Jasper Xbox 360:
http://www.anandtech.com/gadgets/showdoc.aspx?i=3472
It covers:
- What exactly Jasper is and means
- Identification (on the box and on the console)
- Internal, high resolution pics (make sure you look at the galleries)
- RRoD theories
- Power consumption
Somewhat older stuff:
Identifying Jasper:
1. Any console that comes labeled 12.1A on the +12V rail is almost guaranteed to be Jasper. Only a fluke at the factory would result in one of these being Falcon. This can kind of sort of be seen through the packaging with some work. A pic posted by our own RRoD:

Note that 14.2A labels do not mean it's definitely Falcon - it could still be a Jasper.
2. Any console that has 256MB internal memory. Again, we have never seen a Falcon with the increased internal memory and we've never seen an Arcade Jasper without it. Pro Jaspers don't report it, but it's unclear what's really inside.
3. Any console that comes with a 150W PSU. Falcon will not function with a 150W PSU. Jasper, however, would work fine with a 175W PSU and we have definitely seen some 175W PSU's come with Jasper.
4. And finally, probably the most reliable method: just look at the power connector. It would be a pretty serious problem if the factory let out a Falcon with the Jasper power connector. A nice diagram of the various power connectors posted at xbox-scene by fahrenheit:

Lot numbers are not a reliable method yet. 0842 and 0843 lots from both FDOU and CSON have been identified as either Jasper or Falcon. No specific manufacturing dates are a guarantee just yet either. My guess is that 0844 from both teams will ultimately be all Jasper, but we'll have to wait and see.
Also remember that teams TMEM and ADUE are repackaging teams and will usually put a new lot number on an old box. The only reliable way to know the real lot # is to look at the serial number in these cases. the last 5 digits will be XXXYY where XXX is the real lot number. Every once in a while, you will see a 1 week variation between the box and the serial number on FDOU/CSON machines as well.

Looks like we have a probable Jasper sighting! Or two actually!
Yet more evidence is posted at xbox-scene with 12.1A 0843X FDOU consoles:

Both of those xbox-scene threads show Xboxes with 12.1A/150W power supplies and consoles labeled with 12.1A current requirements. This corresponds with what I predicted for Jasper a couple months ago. I firmly believe these are Jasper, even without actual power measurements or even opening the console. I'm sure at some point soon we'll get that data as well to confirm the change. They also have not provided pics of the PSU connector, which would be nice as well.
Looks like all our hard work has paid off!

As of now, we are up to lot 0841 with no sign of Jasper so far. This is based on power consumption measurements with a Kill-a-watt as mentioned in my 2nd article above.
Some newer lots with X attached to the end of the lot # have been discovered, but the meaning of the "X" remains unclear.
I will try to post updates here when there's anything important.
