    Notes:
    - In seawolf2, service mode dip switch turns on memory test. Reset with
      2 pressed to get to an input check screen, reset with 1+2 pressed to
      get to a convergence test screen.

****************************************************************************

    DIP locations verified for:
    - seawolf2 (manual)
    - wow (manual)
    - gorf (manual)
