[edit] Secret Motor

The original Secret Motor was a project by Mike Kan circa 1993 to visualize memory access on a Macintosh using an oscilloscope. The QEMU Secret Motor is an attempt to create something similar using an emulator. It currently consists of a patched version of qemu which prints the x86 EIP for each cycle of the emulated machine, and a python script (based on this YouScope emulator) to visualize that data. TODO: post some video here of the qemu secret motor running.
