The serial number indicates it was probably made in March of 1992. Unfortunately, I have yet to find any catalogs that include a full range of Ibanez acoustics from '92.
This image from a catalog published in December of '92 (which would cover '93 models) shows an AE800 that looks to be fairly similar to yours. The "TV" at the end of the model number indicates the finish color; it could be "Traditional Violin" or perhaps "Transparent Violet".
Here's an image from a 1991 catalog that shows an AE800 in Traditional Violin. This one also looks similar to yours, but appears to have solid rather than split block inlays.
Why the label calls yours an "N840" I can't explain. I'm not aware of an "N" series of acoustics made in this time period.
Actually, I just pulled out Ibanez: The Untold Story (the Ibanez "bible"), and learned that your guitar was part of the short-lived Nomad series. The book still doesn't list an "N840", but they have an "N800" that sounds pretty similar to yours.
As far as a complete history, Ibanez actually does better than most brands in that they publish a fairly complete selection of catalogs online. We're trying to fill in the gaps and improve searchability with this wiki, but we've only just scratched the surface of acoustics.
