Connectcore 9P

Anyone can tell me how to get the hardware manual for this? Need to add either CF adaptor or IDE. How about memory expansion, Digi reports that it is expandable, but there is no documentation. Is there any app notes available at a certain site? Need this info to complete product feasibility. Only found product brief!
