After several fruitless summers wading through ACT-R examples, trying to stand on the shoulders of other cog arch giants , I finally just sat down one afternoon this week and starting "free styling" Python classes to add up to the MHP as diagramed and explained in Card, 86. I'm pretty happy with the result! The MHP, I thought, is simple and powerful enough just to sketch down version really quick. In line with my dissertation, the intent is to extend this to other sensory modalities. 

I created tests very early on because I think this is important for growing the model is seeing what past examples break as it grows and changes. The first test was Example 5 from Card, 86. Pretty happy with the result.
