The memory was upgraded by Sonore by installing the Sonicorbiter 2.8 upgrade 16GB drive.  All I had to do is insert it in the slot and run the update utility.  Highly recommended.

Thanks for the suggestion.  Here is a picture of the under side of the EtherREGEN.  (The rubber feet that came with it are still in the box, as I used a different mechanical vibration damper instead.)
