Where game adjustments are made
Electro-mechanical games are adjusted by moving plugs between sockets, found near the coin door inside the cabinet and in the backbox, often with a label beside them. Most solid-state games use a set of three push buttons on or beside the coin door, with the steps in the manual; untouched games run on factory settings. Some early solid-state games use small slide (DIP) switches on the CPU board, with a settings card often stapled in the backbox.
