Saw one of these advertised locally and couldn't resist. I believe it is a 1991 Dyna Tech Encounter.
It is in fantastic condition looks like it's barely been used since being ridden home from the shop 26 years ago!
It is Deore LX throughout (including pedals) except for the shifters which are Deore DX. The wheelset is LX hubs laced to Rigida Laser 400 grey heat treated rims. Everything on it works beautifully as the owner was a bikeshop mechanic.
It seems amazingly original, even has the Dyna Tech seatpin. I think the tyres, saddle and grips are the only non original parts.
I love some of the features on this frame like the wishbone stays and how over engineered the head tube looks. First thing I've done is put some knobblies on it, hoping to take it out on the trails soon!
