Neo-Geo MVS © 1990 SNK Corp.

A cartridge-based arcade system board. The MVS stands for Multi Video System, and as its name suggest, offers owners the ability to put up to six different arcade titles into a single cabinet, a key economic consideration for operators with limited floorspace. With its games stored on self-contained cartridges, a game cabinet can be exchanged for a different game title by swapping the game's ROM-cartridge and cabinet artwork.
