Wizard Of Wor RAM Boards back

I got them earlier in the week, on Wednesday actually, but didn’t put them in until tonight. I had some time to kill while waiting for the buyer to arrive for the Space Invaders Deluxe, so I put them in the machine and tested it. I was so excited at the possibility of having that game fully working too and ready to sell.

Well, I got lines on the screen. I have no idea what that means, it is weird, fast horizontally moving lines. I wanted to check voltages before putting the boards in, and I got a pinout for the game, but wasn’t really sure because of the weird connections in the game if I should check them at the connection to the cage or at the connection to the one board.

I hope that wasn’t a mistake. I am going to email the guy that repaired them, he’ll probably know the problem, he is really knowledgeable. It almost looks like a sync issue, which is an easy enough fix if that were true. But it looks a little more serious than that.
