 The Microvision was designed by Jay Smith, the engineer who would later design the Vectrex gaming console.The Microvision's combination of portability and a cartridge-based system led to moderate success, with Smith Engineering grossing $15 million in the first year of the system's release.However, very few cartridges, a small screen, and a lack of support from established home video game companies led to its demise in 1981.
