Further, while they could continue to take games they had created for arcade machines to home consoles, this development step cost at least and time to complete, and once on the market, had only about a three-month shelf life before being outdated, making this a risky move.

They jointly developed the concept of using a standalone computer system with a monitor and attaching a coin slot to it to play games on. Bushnell and Dabney worked with Nutting Associates to manufacture their product. Dabney developed a method of using video circuitry components to mimic functions of a computer for a much cheaper cost and a smaller space. Bushnell and Dabney used this to develop a variation
