Hardware, Embedded Systems "In this article, I show at the transistor and silicon level. I've discussed the mathematics of the 6502 overflow flag earlier and thought it would be interesting to look at the actual chip-level implementation. Even though the overflow flag is a slightly obscure feature, its circuit is simple enough that it can be explained at the silicon level."

If I get you right then you're missing the point. Linked article is valuable because of three reasons - nostalgia, debunking and learning value.

Nostalgia and correcting wrong information that is blindly repeated doesn't require clarification.

Learning value does, a bit.
Binary arithmetic didn't change since then and value of understanding quirks of its implementation on real platforms uncovers new territories for some people.

How many OSN readers know how negative numbers are represented in computer memory ?
