Missile Storm © 1980 Sidam.
A bootleg of Atari's "Missile Command".
The game uses an Electrohome G07 monitor, and a unique 3.5'' trackball design. The power supply only provides AC-DC conversion and filtering, power regulation is actually performed by regulators on the game board attached to a large heat sink.
Initial machines have a silver coin door, revised machines have a black coin door, more colourful bezel and slightly redesigned marquee.
