Comet wasn’t the original name. It was going to be 'Riverview', named after the amusement park that used to be across the river from Williams. After discussions with management and some of our big distributors, I changed the name and used one of the roller coaster names from that park. Comet was a common name for roller coasters, along with Cyclone and Hurricane. I figured I might as well keep the theme going.

Here are some pics from Tornado, a Wizard of Oz like game. This is a pencil sketch on mylar as we used to do then. At Bally in 1982 we were working with Marvin Glass, a toy-inventing company in Chicago. they brought in 3 game prototypes that were housed in an "environmental cabinet". So I was assigned to Tornado, Greg Kmiec worked on Demolition (like Earthshaker) and the 3rd game I do not recall at this time. All the games had multi-upper levels and were housed in a Pinball 2000 (like) cabinet. My game had a large "cyclone" funnel vacuum-formed ramp that took balls in multiball and then dropped them to the playfield while the storm effects came and strobe light flashed. You can see the spinner I placed under the funnel to spin the balls away and the shot to the right that went up to other levels above this playfield. So very much a "triple-level" pinball with a video game feel.
