Hi.
I have an issue with a Sega Jamma JVS I/O. This one:
I am using it in conjunction with a TTX.
Problem is that P1 Button 2&3 are shorting. Each individual press on each gives simultaneous input on both.
I have checked continuity at the jamma edge (none), and followed each input trace through to the microcontroller (also good).
I have tested with two different joysticks and with JP1 in both A&B positions. No change.
Is it screwed? Is the microcontroller replaceable?
Anything else I should check?
Thanks in advance...
