Jen,
"I remember when it was brought up from the bottom."
That was in 1901 - you certainly are holding up well !!!
I first heard about it about 15 years ago and thought that was a recent discovery until I read about it.
It seems each time there is a new discovery by using a better mthod of extracting more detail from it the press gets a hold of the story.
The Micro-Tomography done a few years ago has revealed almost everything dimensional about the remaining encrusted parts including about 95% of all the text.

Or the official project site

There are videos of them looking through the device in 2D microlayers - digital sectioning.
So now they think they know how it worked, what it did, even from where it originated or at least the region it was built for.
Truly amazing device and story.
