|Notes (From Undumped Wiki): A vector graphics game mounted in a huge cockpit cabinet that actually swiveled and spun about. The system was called the "XCD-1 Simulator System" developed by Fifty 50, Inc. Vic Tolomei was the primary software developer for Vertigo, Howell Ivy was responsible for the hardware, and Pete Kaufmann and Ken Nicholson designed the graphics and audio respectively.|
This Vertigo was later updated and renamed Vortex, before becoming Exidy's Top Gunner. Vertigo is thought to be the prototype for Top Gunner, using the same hardware, despite being produced roughly two years before Top Gunner. Vertigo-marked PCBs have been found before, but contained Top Gunner ROMs.
According to Howell Ivy, Exidy built about 150 units but only sold a fraction of those. Vertigo was shopped around but never picked up due to poor location test results and excessive hardware costs.
Supposedly a complete example still exists in the hands of one of the above Exidy developers.
