Looking at the development and architecture of the Z80, it appears to be a scaled-down, cost-reduced (in terms of total system cost), clone of the Intel 8080. It only used a 4-bit ALU. I assume this would have reduced its performance considerably.
However, the Z80 out performed the Intel version...

Is there any indication that ...
I've noticed in my physics textbook (and in a lot of other popular sources), that the process of integrating non-constant acceleration to get to a velocity formula, the integrating bounds imposed on the velocity-part seem wrong.
In the above snippet, they're using $v_0$ and $v$ as bounds in th...
