But there are still STC hidden or scattered around the galaxy.

My basic theory is that the Primarch found the STC or maybe replicated a working AI even found somewhere. He then implemented it in his Legion to enhance combat efficitivity. The Emperor got pissed then sent then wolves to bring him down.

The remaining STC or replicas could have been found by Horus or one of his men before the horus heresy. that knowledge was then given to kelbor-hal (the Kaban Project shows that some of the adeptus mechanicus broke their own rules)
