They used to. CS 1st year used to include constructing circuits from base gates and driving hex LED displays, simple calculator, Carnot maps, flow diagrams, stuff which goes strongly to boolean logic and gates. Plus machine code, and one higher level language.

I think now there is a stronger tendency to partition the space into hard ware and soft ware and so the hard ware courses are electrical engineering not computer science, and the computer scientists are taught an ideal machine abstraction.
