[ExI] Is the brain a digital computer?

This is like arguing that the letter Z has a specific mass and then claiming anyone who disagrees is a dualist of some sort -- whether of property, of substance, or of whatever.

Yes, and I liked your analogy. You argued that conscious thought arises as an emergent property like the surface tension of water. I've made similar analogies here in which I compared consciousness to the frozen state of water. I like your analogy but I like mine better: the brain enters a state of consciousness like water enters a state of solidity.

I wonder now if you want to defend property dualism. 

I reject both substance and property dualism. On my view, at time t when the brain exists in conscious state s, the conscious thought at t exists in/as a particular configuration of brain matter. That configuration of brain matter at t has mass.
