So I probably didn't take as many pictures as I should have here, but I just wanted to get to a point where I could actually play the game!
The first thing I did tonight was pilfer one of the speakers from my mostly empty Track and Field cabinet. (Not my working one.) I cleaned it and set it up. Eventually, I wired everything correctly, and held a big breath as I turned on the machine. I heard a FWUMP and the crackle of static. I also heard the loud noises of life from the PCB, so I immediately turned down the volume.
The grounding wire on my video plug was loose, so I took the molex and soldered the connectors instead of crimping them and tried again.
I didn't see a picture, so I fumbled with the flyback and saw a an image. "DHCP Error" was coming up. It was also upside down and mirrored. I turned off the machine and flipped two yoke wires. Unfortunately, the AC wires were loose and I took the lower plug housing off and attached them without the lower plug. I had to do this on my TnF as well.
I was still getting the DHCP error because I am not connected to the ethernet yet so I needed to change the setting. Normally, you do this by holding P1 Start while turning on the machine. It wasn't working.
I then inspected under the hood. The buttons weren't pushing the microswitches down. I angled them up and P1 worked, but P2 didn't. So I was able to then turn off the online function.
So, it works and functions. Still has some more work but at least it is playable. The main one for me is to figure out this interference going on in the image. Odd.
