1996 Specialized Ground Control A1 Comp???

1996 Specialized Ground Control A1 Comp???

Please clear my confusion. Is this bike the 1996 Specialized Ground Control A1 Comp, or the base model 1996 Specialized Ground Control?
It has AIM on the rear chainstays, what does this mean?
The rear triangle tubes are different front the front triangle.
The front triangle is Prestige tubing, a decal reads "handmade in Taiwan".
Here are some pictures:
