First, Welcome to HRC!!
It appears that the only way out digitally is through the SPDIF port, but that will probably only get you two tracks at a time, and you'd also need some sort of similar SPDIF interface on your computer.
It also appears that the CD drive can be added as an option. Maybe you can pick one up somewhere for cheap?
