Hi,
i have a problem with a System 1-mobo, the joystick-inputs are not working. Everything else works like a charm, except the joystick controls won't work. It's a TTL type motherboard (revision C), which should work with all 5 daughterboards. I have 2 daughterboards (Indy + RoadBlasters) and it's the same problem on both, so it must be motherboard-related.
I know by now the LETA ist working (switched one from a working Rampart pcb). I also verified the ADC0809 is working (bought a new one). I measured 2,5 V on the joystick inputs (J102) and no voltage at all on the trackball inputs (J103). Funny thing is that the gas pedal input is working on RoadBlasters through J102 (which is the joystick down-signal on Indiana Jones). Also all signals from J102 go to 0V on the ADC if they're grounded, so I assume everything is ok between ADC and J102.
My tools are multimeter + logic probe. Has anybody a suggestion how to go on from here? Any help would be much appreciated!
Cheers,
Wurst
