Hey..I'm new to this forum and I just read your post about reverse engineering the OS on the Z2 to possibly upload your MP3s directly to the HD. Anybody know where I could get a copy of the OS and EPPROM? Any other supporting information would help also (ie: What OS is it, CPU type, etc.). I wouldn't mind taking a crack at it; I do program in multiple languages (VB, C/C++, Assembly, PIC) so I would love the challenge...if it hasn't been solved yet.
