In 1982, Universal Sales made arcade history with a game called Mr Do! Instead of selling dedicated Mr Do! machines, Universal sold the game as a kit. The kit came with a customized control panel, a computer board with Mr Do! read-only memory (ROM) chips, stickers that could be placed on the side of stand-up arcade machines for art, and a plastic marquee. It was the first game ever sold as a conversion only. According to former Universal Sales western regional sales manager Joe Morici, the company sold approximately 30000 copies of the game in the United States alone.
