It is a pretty basic hybrid/"comfort" style of bike, what are you looking to know? Value unless sentimental value is pretty low and putting the absolute factory spec parts on it will be a very expensive endeavor. Cheap 7-8 speed stuff can be bought new pretty easily at your local shop as needed. If you are looking to mountain bike with this I wouldn't recommend it as those parts were not designed to handle it, it is a bike built for paved roads or light off-road trails but not actual mountain biking. If you are looking to ride it I would fix your stem and handlebars as the angle is too high on the stem and the stem might be high so check to make sure the minimum insertion line is in the frame (not just the threaded headset). If you want to invest money into this because it has sentimental value than you can find riser bars and sweptback bars that will put you in a more upright position.
The triple triangle frames are cool though and the color is great but I am partial to variants of B. Racing Green. However the bike overall was an initially low cost bike so only invest if you really love it and aren't looking to try to make money on it.

Thanks for the replies but that’s not what I asked for. I’m looking to get bike specs and or
description from the serial number if that’s possible. GT has gone out of business I’ve heard and a local dealer can’t help. I’m wanting to sell the bike and would like get as much information as possible.

If you are trying to get highest value get the bike as clean as possible adjust the handlebars and stem to the correct position and follow the rules for taking bicycle photos and take lots of good photos and stick to the drive side. https://theradavist.com/photographing-bicycles-how-to
In the end the effort will probably net you $20-100 but certainly you can always try to ask for more. But a 26 year old bike that was around $400 bike new doesn't hold much value.
This can be a starting gauge for pricing some people don't love it because there area is really good for sellers and you can get more and some are bad and you get less:
