have a 60 in 1 friend bought and has me setting it up..
well 60 in 1 works fine plays etc .
BUT no other board I hook to the jamma harness does only the 60 in 1 (BWT they all work fine on my test rig)
tested goldentee cps1 cps2 and few others nothing
tested voltage from his pc type supply 12v was running 11.7 figured wasn't to low but might be it so put it on a good switcher still no go, all voltages are good. and 60 in1 running off switcher now nothing else .
checking all jamma harness pinouts etc all seems good video ground was not connected at 14 was wired into ground cluster so I wired it to 14 just in case no help.
just weird to me
he wants to be able to use other jamma boards in this rig .......
