Nintendo VS. System game instructions.
The Nintendo Vs. System is a coin-operated video game platform designed for two-player competitive play using the VS. UniSystem or VS. DualSystem, arcade system boards based on the Nintendo Entertainment System. Many of these stand-up or sit-down arcade machines had two screens and controls joined at an angle. These games were arcade ports of home video games for the Nintendo Entertainment System, thus they could be sold cheaply to arcades in the late 1980s. (wikipedia)
