Compaq's PJB-100 MP3 Player Open-Sourced

spludge writes: "Remember the PJB-100? The portable 4.6 gig hard-drive MP3 player -- the one that did not have support for Linux? Compaq just released all the code to communicate and control it under the GPL! All the code and documentation is available for linux and for windows. Read about the details and what you'll need online. Lots of information about how the PJB works and how to communicate with it via USB."
