Article from 2017 looking at the PDP-11/45 originally used to create the Death Star Trench Run simulation in Star Wars from 1977.
The article mainly talks about the people and the computer graphics department at the University of Illinois at Chicago who created the simulation. The embedded video in the article shows the computer itself running portions of the original simulation.
Several years ago, before DeFanti left EVL in 2004 to join the California Institute for Telecommunications and Information Technology, he gifted the computer to Steve Heminover, a former student. Heminover — who started Aura Technologies, an electrical design firm that provides lighting effects for Major League Baseball, the United Center and the Bellagio hotel in Las Vegas — explained: “I could not let UIC throw these things away. They’re pieces of history, the computers that led eventually to Pixar and the digital effects we see all the time now. These, in a big way, are where it all started.”
