I am curious about how people debug their code once they have burned it
into the chip and it does not work correctly.  Would appreciate any
feedback I can get.

I'm not talking about the commercial guys, now, with their zillion-dollar
systems, but the poor hobbyists (like me) who have a breadboard, a chip, a
few components, and a simulator.

Simulators are wonderful, but at some point you have gone through the code,
and it all looks correct; you have run it through the simulator and it
works perfectly, you burn it into the chip, and BAM! it does not work. :-(

So how do people debug it at that point?  (I have some ideas, but I am sure
there are a whole raft of things I have not thought of).
