If anyone is interested, I can also post my tear-down of the classroom connectivity kit and the StreamSmart 410. My current project with the Prime is to investigate the possibility of better integration between programs and external sensor inputs.

I'm not so much interested in the Linux project but I do find the hardware mapping very useful (though tedious). Back in during the HP48 days, there were a number of hardware mods that were possible due to hardware pioneers: home made RAM cards, sound cards, RAM expansion to the G versions, etc. etc.

Perhaps there will be similar projects for the HP Prime. However, in order for that to fully take place, I imagine that we would need HP to give us low-level access somehow (such as was done for the HP48 through HP50 series) in the form of SASM/MASD.
