As a long time Zeo user, I am pleased there is a new ZeoViewer with a CSV file export compatible with SleepyHead. This viewer is for Bedside Zeo models only.
The new viewer (by woodinblack) is greatly improved over the java versions and will read both encrypted and unencrypted Zeo data files.
Sorry, I don't have a enough cred here to post links and images yet, but more about the Viewer, it's use with SleepyHead, and images has been posted on a DME sponsored forum.

Get your old Zeo out and put it to work again.
