Hello there everyone, my name is Rick Medina and ive been an arcade collector for quite a while now, I hope someone out there can me with this project im working on, i currently have a dark legends cabinet, and im trying to make it so i can switch between dark legacy and sportstation using the jamma switcher from mikesarcade, You see I bought the sportstation upgrade kit and the nba showtime board set on ebay, the boardset came complete with the aux board and the i40 board with the cables for the joysticks and buttons located on 1 end of the harness,and connected to the i40 at the other end it also came with a small cut off 9 pin harness on the p1 connector on the i40 board, and 4 more connectors with male jumper pins coming off the other end of the harness near where the control cables connect to the i40, i have found out that those cables have to do with the playing buttons for the game, buttons a,b, & turbo as well as the start for each player, the problem im having is im not sure what goes into the p1 connector on the i-40 board, i have checked the wiring diagrams in the manual and it says that p23 on the sio main board goes to it, but if you look at the pinouts of p23 it clearly shows that it is a coin door connector, in the same manual it also describes the pinouts on the p1 connector on the tiny aux board and they seem to be what goes into the p1 on the i40 board but nowhere does it show the actual connection between the 2 boards, also i noticed that the connectors that come out of the i40 board are only for the buttons not the joyticks, so im not sure where those would come out of, other than player 4 which seems to come out of the i40 board with all the wires nessesary to connect it, currently player 1 & player 2 joysticks are working off the jamma harness but they are acting really wierd, and i confirmed that switch 1 on the u12 dip switches is in the proper 49way joystick position and not the 8 way, but i have tried it both ways just in case, they continue to act randomly i cannot get them to work properly. Any help anyone can give me would be greatly appreciated.


Many Thanks
Rick
