In spring 1983, former MOS Technology engineers Robert "Bob" Yannes, Bruce Crockett, Charles Winterble, David Ziembicki, and Al Charpentier formed Peripheral Visions. The team had designed the Commodore 64, and hoped to build another computer. To raise funds, Peripheral Visions agreed to build a computer keyboard for the Atari 2600, but the video game crash of 1983 canceled the project and Commodore sued the new company, claiming that it owned the keyboard project. Renaming itself as Ensoniq, the new company instead designed a music synthesizer.
