Sega Tracer released in 1976 was a compact version of its predecessor Bullet Mark. A bridge between electro-mechanical arcade (known as EMs) and video games, this discrete logic twin shooter has a number of noteworthy features. Using a mirror, the monitor is reflected from the bottom of the cabinet giving the illusion of the targets being further in the distance. The bezel displays the current score setting and large faux LED scoring. When shooting both twin tommy guns flash red LEDs in the tips and shake with a RAT-AT-TAT-TAT. This effect is really wild. Watch the video below the fold to get an idea.
