I wrote VGN asking for this info, so I'll paste what they posted:
"The Gonz has written us asking to post a request for information regarding Exidy's 1976 arcade game Death Race. He is looking for screenshots of the graphics ("the closer and bigger, the better"), sound samples from the game, and any other information that can help to write a simulation of the game. It's not known if this simulation will be hardware, or just a clone of the game, but either way, I think it's pretty cool You can send any information that could be helpful to this project to gonzo@atari.net."
So there you have it. If you can help, please email me. I also plan on writing simulations of the original Breakout, Steeplechase, Stunt Cycle, and other pre- CPU games in the future.
Thanks!
The Gonz
