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."

for example the Z80 is still sold and used in many of the CCC MP4 players sold on Chinamart, one can pick up one of those and try hacking on that.

isn'T the z80 the architecture with the most produced units?
