Question
JimD
Just creating a new multicade with a JAMMA 412-1 ELF PCB and I connect 'everything' and it starts up 'fine', I can hit the S1 test button to go into setup mode ok (so that button works). AND in test mode I can see that Player 1 - START (PIN 17) and Player 2 - START (PIN U) work fine but none of my other buttons (I have 3 P1 buttons - PINS 22-24, NO P2 buttons) connected as well as the P1 joystick (PIN 18-21) - NO P2 joystick.
I also have a trackball connected and that works fine (through a trackball cable connected directly to the PCB) - that is how I am able to navigate the menus since the joystick doesn't work.
The Joystick, 5 buttons (Player 1 Button 1-3, P1 start, P2 start) are all grounded with a daisy chain ground that starts at the two start buttons that work, then to the 3 P1 buttons then to the joystick. I've tried reversing the grounds to see if there is a problem in the daisy chain - nope...
I have made sure the microswitches are connected ok AND I've even swapped the microswitch from the working P1 Start button with the P1 buttons and no difference.
Now, I have NOT connected the PIN 28/F ground wires to ANYTHING... (and I haven't done anything with PIN 27/E which are supposed to be Buttons 6). But if that were the issue, WHY would the two start buttons work???
Any advice here?
thank you!
