DIP-SWITCH TESTS

Select DIP-SWITCH TESTS at the Diagnostics Menu. Two 8-position DIP switch banks reside on the SIO Board. DIP-Switch Tests allow you to check the position of the 16 switches in these banks. You can change the setting of any DIP switch without removing the circuit board cage.

The menu displays an illustration of each switch block and the current settings. You can change DIP- switch positions with power on. Set any switch, and then check the menu to verify that the new setting is enabled.

Refer to the charts for assistance in choosing switch positions. (* indicates factory defaults.) To exit the DIP-switch Test, press the left control button (inside the coin door).

Game-Selection Switch. Select NBA Showtime or NFL Blitz by flipping switch 8 at DIP bank U13. Then power down and up again. After you change the game play, you must change game artwork.
