Dig Dug Restoration by a Complete Noob
Kevin Mullins:
That is the correct ARII board for Dig Dug.
Hard to really tell in the pics, but check all the resistors closely and with a meter to see if any are open (burnt/broke). Especially like R29, R30 I believe.
That pcb edge connection already looks like it's has some soldering repairs done to it on the main board, so I would double check for good solid connection with the wiring harness plugged in. That will cause those resistors to burn up that I mentioned and you will loose voltage going to the game board.

Yep. Shame it's missing, I could have used one ;)
Seriously, if you can get the Sanyo working, it will be a great monitor. Off all my cabs the Sanyo (not 20EZ, earlier version) in my Nintendo cab is by far the best looking of all of them. And yes it has been running quite a bit because there is a slight Radar Scope burn-in AND I haven't even re-capped it (except for the fold-over cap). And even so, the picture is like new. Ask Polaris he saw it yesterday and was amazed :D

Yeah, I saw that too, but didn't see anything for it to plug into in the cabinet.
Maybe that was a quick fix by someone because the edge connection was bad.
It definitely appears that the edge has been repaired or at least has something going on there. But the original wiring still appears to be in the harness correctly. And the spots that look "odd" are obviously power/ground related.
:dunno
Can you get a decent picture of that pcb edge connection without the harness plugged in?
Maybe we can see something going on there as well.

What I'm saying is it's not "missing" .... it was never there. ;)
And yes, these are damn good monitors when working.
As long as the flyback doesn't go out.....it'll last and look good forever.
ChadTower:
Well, those Atari games are known for having truly crappy connectors... and it doesn't look burned... so someone probably just bypassed the connector rather than repin it. At least they put a molex on it so you can still remove the PCB.
