This pcb uses the basic Jamma connections plus a few extra connectors. There are 2 connectors on the lower board...a 6-pin and a 5-pin. The 6-pin is for connecting a 360º steering wheel. The pinout is as follows:
In order to use a 360º steering wheel you must put dip switch 1 on at the 4 position dip switch located next to the header connector & dip switch 4 on / 5 off at the 8 position dip switch located at the pcb right side.
The pinout for the 5-pin to connect up a 270º steering wheel is as follows:
In order to use a 270º steering wheel you must put dip switch 2 on at the 4 position dip switch located next to the header connector & dip switches 4 & 5 on at the 8 postion dip switch located at the pcb right side.
When using the 270º steering wheel you must center it. To do this, align the wheel to straight ahead position & hold the start button down while powering up the game, and wait for screen to say "wheel adjusted".
8 position dip switch functions:
Test mode....dip 1 on....choices are "input device check", "system setting" & "sound test". Use start button to select your entry & use accelerator button to change.
Input device check is the standard I/O check for testing buttons & wheel.
Systems setting is for adjustment to coin/credit, difficulty, language, flags, anthems, & clearing game records. Any changes made must be saved before leaving via selecting "memory the setting & exit".
Sound test is obvious with the exception of sound on demo mode. To toggle the sound in demo mode on & off you need to press the start button & the accelerator button at the same time.
