When I tried the link in bishoplogan's post to
http://www.ebooktechnologies.com/devices.htm, it didn't work. So I tried going to just
http://www.ebooktechnologies.com, and saw this message on their site:
"eBook Technologies, Inc. is excited to announce that we have been acquired by Google. Working together with Google will further our commitment to providing a first-class reading experience on emerging tablets, e-readers and other portable devices.
This must have happened sometime in early 2011, since the info on the page says it was last updated "Friday, February 18, 2011 6:59:27 AM"
For legacy eBook Technologies downloads, please visit the Wilde Technologies download page." That link takes you to
http://www.ebooksystem.net/support_download.htm.
It has links to drivers, conversion tools, and tools.
So for people who search for information on ETI-1, maybe this new information will help you find what you need. Things are changing, so I guess I will download the drivers in case that site goes away!
