Dell Digital Jukebox

LambdaCalculus:
I may not be much of a real coder yet (I'm still a padawan  ;) ), but I can at least be one hell of an information ferret.

I recently purchased a 1st generation Dell Digital Jukebox from eBay for pocket change. The DJ has a bad hard drive, but I can easily fix it. Anyways, seeing as how the TMS320 and its derivatives seem to be a big topic going around due to the Creative ZEN Vision:M port, I had a notion:

Once one TMS320-based device is up and running, how hard would it be to bring in more devices that use the same family of CPUs?

Despite being branded by (ugh) Dell, the Digital Jukeboxes were rather interesting devices. Basically a rebadged Creative ZEN, the Dell DJs had most of the same features as Creative's early players, but with some cosmetic changes.

I'm currently trying to gather up as much information about the hardware as I can, but I wanted to know if anyone else would be interested in seeing the Dell DJ become a proud new addition to the family.

JdGordon:
I think the tms320 ports will all be similar to the portalplayer ones, most of the firmware code will be the same with various changes to suit to specific model

LambdaCalculus:
Very true, I say. Once the core works, we can just build around it.

The only problem I'm having now is that the Dell DJ's drive is toast, but like I said, a friend of mine has a replacement waiting for me which I'll be picking up later this week. And I'm on the verge of banging my head on a brick wall trying to mount the drive on a Windows box; the bloody thing needs a driver from Dell. Only thing is, however, that the driver doesn't do anything.

Once I finish fixing up my laptop, I'm going to see if I can mount it and at least start gathering the partition table for the hard drive... it's the least I can do right now.

LambdaCalculus:
I just managed to get the Dell DJ back up and running. I'm currently looking for the data sheets for the hardware in the device. I should have a wiki up for it soon enough... and hopefully faster than the Archos AV1XX page.  :P

Can anyone else help supply a little extra information about the Dell DJ? I am looking for information about the Generation 2 and the DJ Pocket, specifically.

LambdaCalculus:
First findings on my Dell DJ; sorry for multiple posts in a row, guys.

Hooked the DJ to my Linux laptop and ran lsusb -v on it. Here's the results:
