There is a wee tiny bit of tech in the southern country of Bor, inhabited by dwarves. The dwarves have guns and stuff, but don't use them all that often - much like guns in the Medieval period. And come to think of it, the dwarves of Bor are an inspiration for the dwarves IMC. The Drakkarim of the Darklands have ironclad warships and that (though don't know if they do in the RPG, to be fair) at the time of the original books, and some races (I'm thinking mainly the crocaryx [dragonfolk]) have gun-like weapons. But really no tech beyond that which you could find in any other DnD setting - definitely a steampunk setting, by any means.
