Worksop
Quoted from dzorbas:Okay guys, after a few weeks of vacation time I'm trying to pick this up where I left off!
barakandl, you mentioned the bridge. Is that what I have circled in the image? I haven't pulled the sound board out of the game yet. I'm assuming that I will be able to test the individual diodes from the back side of the board or am I mistaken?

With respect to the ball lock that wasn't working, after thinking I had some major issue (and I probably still might) a bit of wiggling of the 2J3 connector seemed to get all the switches working again. That probably means that I might have to do some work on the connector at some point, perhaps reflowing the solder joints. I did learn a bit about the switch matrix though.
For now, I'm okay, so the focus is back on getting the sound board working.
After chasing my tail on a couple of system 6/7 games with switch issues I replace both male headers and re-pin the female connectors on 2J2 (?) and 2J3 as a matter of course.
