Well, the guy at VCF mapped the address, data and register lines of a
Pentium (or 486, can't remember) to an oscilloscope. The scope would jump
all over the place based on what was being done inside the CPU.

I ended up with a copy of the video. It's cool to watch for about the
first 10 seconds and then you've seen it all. The video goes on for about
an hour showing the operator of a windows PC do different things. Yeeha.
