The Soul of The Sims, by Will Wright -- Macintosh HD:XmotiveHarness:src/Motive.c -- Tuesday, January 28, 1997 / 9:25 AM

I had just started working at the Maxis Core Technology Group on "Project X" aka "Dollhouse", and Will Wright brought this code in one morning, to demonstrate his design for the motives, feedback loop and failure conditions of the simulated people. While going through old papers, I ran across this print-out that I had saved, so I scanned it and cleaned the images up, and got permission from Will to publish it.
