Grand Products Inc.

Grand Products Inc. is a coin-operated amusement manufacturer founded in 1985 in Elk Grove Village, Illinois, by David Marofske, who had started at Midway Manufacturing and risen to president of Bally Midway during the arcade boom. In 1986 the company released its only pinball title, 301/Bulls Eye, sold as a conversion kit: operators installed a new playfield, backglass, sound board, and ROM set into an existing Bally solid-state cabinet, reusing the donor game's electronics.

By 1990 Grand Products had moved on to infrared ball-tracking games published with the developer Incredible Technologies, including the redemption game Dyno Bop and Slick Shot, a video pool game played with a real cue ball and cue sticks. The company still operates out of Elk Grove Village under Marofske's son, David Marofske Jr. — today in electronic wire and cable harness assembly rather than amusement manufacturing.
