Monitor Placement
Change the Monitor Placement (horizontal, vertical) to suit the game being used.
If there is no mention of the correct placement for the monitor in the documentation provided with
the game the monitor should be set to horizontal.
Horizontal Scanning Frequency: 15.85kHz/31.69kHz
Depending upon the game either a frequency 15k or 31k Hz will be supported, or in some cases
both.
Use the DIP SW (Dip Switch) 3 on the SystemSP board to specify the frequency output.
Be aware that an interlaced display may cause a minor amount of flicker or image shaking to
occur compared to a non-interlaced display.
Also, if the cabinet’s monitor does not support an interlaced displayed, noise on the screen or
other display errors may occur.
Among those games that support both 15k/31k, some are strongly recommended to be run at 31k.
If these games are run at 15K, a warning message will be displayed when the game starts up.
When a SystemSP board is initially shipped the DIP SW may be set to 15k or 31k depending upon
the enclosed game. Before placing the board into the cabinet, be sure to check the DIP SW and
perform any changes if necessary.
This game requires DIP SW 1 and 2 to be OFF, and 3 and 4 to be ON.
This game runs at 15k.
