Tron Cab I got it home but man is this thing in rough shape. http://flic.kr/p/cMbrey The interlock was the problem for the not powering up. Someone had replaced the top back panel with 1/4 inch wood and it had bowed over time from the pressure. The game still has PCB issues but the...

I don't own a SFII but sometimes this sort of thing can be caused by a power supply that is not putting out the correct voltages. Take a look at the manual and the powersupply and use a multimeter/voltmeter to makes sure that you are getting the proper voltages. Even if this isn't the cause...

Thanks everyone for the help! The ram was my next guess. Though I wasn't smart enough to think of switching the chips around. I was going to just replace them but switching them is a much smarter idea. If the frog is green and I have a new problem then there's the issue. Thanks for the...

Crap, the manual has a misprint but I'm not sure which one is right. http://www.arcade-museum.com/manuals-videogames/F/Frogger.pdf On page 65 it lists IC 37 as a 74LS27 On page 69 it lists IC 37 as a 74LS161 I know that I used 74LS161 but I threw away the old chips and I'm not positive that...

I have a frogger cocktail that has a frogger character problem. The frog is red and black. When you jump into the road the frog disappears entirely. After you get across the road he appears again in red and black. I have been looking at the manual...

I flipped one of the switches and was able to center the screen. I have a bit of pin cushioning but MUCH better image then before!

Here is a picture of the board.... (not my picture) http://forums.arcade-museum.com/attachment.php?attachmentid=36021&d=1274929753 I doubt it will help but does anyone know what the two switches on the left hand side do? Thanks, Nick

I wanted to add that I can not find a manual for this board so I had to just look at the values of the caps in place. I have looked at manuals where people said it was for this board but they don't match up. The cap location are not the same at all. My board also has a daughter board for the...

I have a lethal enforcers cab where the guns didn't work. I replaced the power supply with a brand new one but still no luck even with a steady 5 volts to the guns. The monitor was dimmer then it should be so I tried a cap kit to see if I could get the guns working. Well the good news is that...

I blew a few fuses because of a fried Tantalum cap. It is under the heat sink of the logic board (sound board) on the sides nearest the edges. So in your picture it would be like the blue cap that sticks out from the heat sink, in that position but on the other side. Mine was black, and when...

It's the regular space invaders roms. From what I have read, you can use a SID sound board in a SI game board but not the other way around.

When I first powered the board on the Tantalum cap under the heat sink smoked and the game made a lot of noise. I have replaced the Tantalum cap and now I have the problem that I described. Assuming that the problem came from that bad cap, the line goes from the connector to the cap then into...

Any idea where I should start looking for the problem? I could replace the caps on the board easy enough but after that I'm not really sure where to start looking.

I believe that I have a watchdog problem on my Space Invaders cab that I am restoring. If I plug in a Space Invaders Deluxe sound board the game plays fine. With the Space Invaders sound board it just keeps resetting at the exact same point just a few seconds into the demo screen. I can coin...
