Now that I’ve cleared the appropriate IP hurdles with my employer, I’m able to make the CAD files available for the arcade boards I’ve blogged about recently. Included in this repo are adapters for:

• TRON / Discs of TRON
• RoadBlasters
• Spy Hunter
• Universal JAMMA Edge
• Williams JAMMA Edge

I haven’t blogged about the Williams interface, however it is essentially a universal edge with a signal combiner, op-amp, and -12V boost inverter to support Williams games. I’ve Joust and Defender running on it at home quite happily.

All of these CAD files are for educational use only.
