Now that I got my Pacman working it's got me in the mood to get some of my projects games running. I bought a dedicated Frogger back in 2005 off Ebay because it was local to me. I only paid $188.05 for the game and it was in pretty good condition but it had a monitor sync problem. It's been out in my garage all this time and I used it to test parts of my Pacman monitor as they are both K4600's. Before I pulled the monitor out of the cabinet after moving the game so I could get to the back easer I noticed the game had developed a problem with the graphics. Now the monitor is rebuilt and ready to be installed but now I have to figure out what's wrong with the board. I removed the board and brought it inside the game room to work on. I had bought a Konami 36 pin to JAMMA adaptor years ago for a Gyruss board so I figured I could use that on my JAMMA cabinet. I hooked it up and got the same problem it had in the Frogger cabinet. I removed all the ROM chips, pins and sockets looked good and clean but the Z80 CPU had rotten legs. Two legs broke off and was left in the socket. I picked them out and put a new Z80A in the socket and fired the game back up and I still had the same problem. I posted a video on YouTube and also here are a few pictures. I am hoping someone has seen this problem before and can point me in the right direction. Looks like it time to get the logic probe back out.
Thanks for looking.
