Thanks for the welcome and your fast response.
You are absolutely right about the device
I feel no need to get another ebook reader anytime soon.
I have checked the firmware and it is at version 3.3. It seems not to be registered to anybody and most likely was never migrated.
Found the impserve.py and already made all the replacements. Just figuring out how to compile ebookutils with the changes included.
I have tried most of the other software available for serving content but will be looking closer into all the conversion options.
