6. PHICS MESSED UP GAME DOESN T DISPLAY PICTURE ADDITIONAL HELP AND INFORMATION LF Introduction The MultiJAMMA system is designed to allow up to eight JAMMA standard arcade game boards to be connected in a single cabinet and allow easy electronic switching between the games with the push of a button A MultiJAMMA installation will consist of a MultiJAMMA Controller and anywhere from two to eight MultiJAMMA Switchboards The Controller coordinates switching between the games while the Switchboards handle the actual electrical signal routing Switchboards connect to the MultiJAMMA Controller by a 40 pin ribbon cable JAMMA Game boards plug into the Switchboards and the MultiJAMMA Controller plugs into the JAMMA harness in the arcade game cabinet Because most arcade game power supplies are designed to run a single arcade game board you will need to add additional power supplies to the game cabinet to power all of the boards Controller Features Each Controller board can switch up to 8 JAMMA games with the push of a button Works for coin operated or free play Coin drops only credit the selected game Service switch only credits the selected game Free play mode generates virtual credits so it works with game boards that don t have a built in free play setting Early classic games etc Allows boards with or without built in free play settings to be easily mixed and m

8. ded with the MultiJAMMA The MultiJAMMA will use the power supply in your JAMMA cabinet for its own power but additional power is needed for game boards connected to the MultiJAMMA Switchboards The switching power supplies used in personal computers are recommended for use with the MultiJAMMA Power requirements for the additional power supply s will vary with your games but in general you can use the following guideline 1 Assume 5 Amps of 5 Volt power for every game board 2 Assume 1 Amp of 12 Volt power for every game board 3 Some 5V current for some games only When in doubt go with bigger power supplies Following this example a full 8 game MultiJAMMA would require 8 5 Amps 40 Amps of 5 Volt power 8 1 Amps 8 Amps of 12 Volt power Some 5V supply Since most PC power supplies are rated for about 20A of 5 Volt power a safe configuration would be two PC power supplies one for every four games The 5 Amp per game rule of thumb already has safety margin calculated in so being right at the rated limit of the power supply is OK since the rating should be overkill already Users with electronics experience can measure the current being drawn by their games and select a power supply more specifically suited for their application if so desired If in doubt buy a power supply that you know supplies more current than you need Don t skimp on buying the power supplies either they re supplying power to your

18. s when using the MultiJAMMA In particular Monitor selection and Power Supply Monitor Selection The MultiJAMMA will work best with an auto sync multi sync type game monitor In general this is most any monitor made after about 1994 or so and most any that came in a factory built JAMMA cabinet but there are other ones as well It is possible to use the MultiJAMMA on an older manual sync monitor but depending on your game boards the display on some games could roll or not sync without manually tweaking the monitor controls when you switch games To test your monitor you can do the following 1 Collect the game boards you would like to use with the MultiJAMMA 2 Oneata time plug in each game board and turn on your game Make sure the picture looks normal without having to make any adjustments on the monitor If the monitor did not sync on one or more of the games or if you had to manually tweak the monitor to get it to sync I warned you not to the MultiJAMMA will act the same way So if one of the games rolls on the monitor without the MultiJAMMA it will do the same through the MultiJAMMA too You may be able to set an older manual sync monitor to a setting that will sync for all the games through trial and error It will depend on the monitor and the games however Power Supply Selection You will need to add an additional power supply or two to your game cabinet to supply power for the game boards It is not inclu
