DIPs (DIP switches) can refer to 3 kinds of configuration interface:

Hardware DIPs: the real DIP switches, which are found on MVS systems to set the cab's configuration.
Software DIPs: parameters for games like difficulty, lives... They're in the form of data stored in the MVS battery-backed RAM.
Debug DIPs: normally not accessible. Pair of bytes used by developers to activate tests screens, hidden game modes, job meters...
