As of this week I'm the proud owner of a very nice condition Namco Cyberlead 
The cab is equipped with the original Namco JVS/Jamma adapter board and I'm having some issues with it...
When a JVS pcb is hooked up, all buttons and controls work.
When the adapter and a Jamma board is hooked up, button 2 of player 2 does not work. But all other buttons/controls do!
I checked all wiring and all looks good (otherwise JVS pcb wouldn't work as well), I also check the wiring on the Jamma side, and there is continuity from the Jamma connector to the adapter pcb.
Only logical explantion I would have is the adapter being defective...
As a temp fix I wired P2 button 2 directly to the Jamma connector, this works, but is not the way I intend to use it permanently...
