If you look over
here, you'll see that I'm working on a replacement circuit board for the DMS Cradle which should work better with modern operating systems. I'd really like to get a Mac owner (preferably in the US) who has a Phatbox to test out the board before I start producing them. If you're interested, all you need to do is let me know, and promise to return the board when you've finished testing and report back how it worked.
Note that since this is a prototype for development, you'll need to remove the hard disk from your DMS and mount it on the prototype (the prototype only has a 44-pin mini-IDE connector, not the normal DMS connector). If you've hacked your box and replaced the drive, this is just as easy.
