  1. Ice cold beer issues…

    Which fuse is F2? I looked at my Zekes Peak, through the coin door, and took a picture. I do not see the fuses on mine as F2, they are not marked on mine.
  2. Wanted, Journey Bezel and Marquee

    Just picked up a converted Journey with everything in it still, except main board, bezel and marquee. This old game is out of stock on the repro with no ETA. Looking for a repro or an original in decent condition.
  3. Professor Pacman - Complete board replacement solution

    I am interested, sent you a message.
  4. Monitor loses and gains focus

    I had a tube that did the same thing when I bought a game. I did the same thing and recapped it. Still had the problem. Turned out someone before me broke a pin on the neck that just happened to be for the focus. The pin was still there and was visible but I could pull it out. I tried to use...
  5. Nintendo Vs. Color Problems

    I don't really have any knowledge on these boards or reading schematics real well but perhaps maybe a capacitor or bad transistor in that area? I personally would check all of those around the color pots. One of the caps looks a little weird to me, I believe it was C31 but it could just be the...
  6. Looking for an arcade game from my childhood

    I believe the game you are looking for is Uni wars or Uniwar S. It is on YouTube if you look up Uni wars.
  7. SkeeBall issue with scoring, any thoughts?

    I am trying to go off memory here so I may be wrong. My unit is not at my place so I cannot double check on mine. If it is a H or S model, I believe there is a microswitch in each scoring hole. As the ball rolls down, it makes contact with each switch below it, adding up the points (I believe 10...
  8. Cloak & Dagger Repro (Defender conversion) Control Panel & CPOs on the way!

    This is great! I will take 1 control panel with the CPO please.
  9. Taito Ice Cold Beer: NOT SO Dead Anymore!

    Hopefully this works out for you. Did you test that chip before ordering a new one or did you just order one? Please update with your results when you get the chip.
  10. Data and address bus questions

    I checked the NMI pin last night and it seems to be pulsing the same as my working pcb. I poked around the bad pcb on the lines that go to the NMI anyway, nothing stood out to me. I will look a bit more over the weekend and compare to my working pcb and see if something stands out. Thanks for...
  11. Data and address bus questions

    Thank you again for a reply. This does help clear things up a bit. This would explain why looking at the schematics I kept wondering where the information traveled back to the cpu from areas like the foreground and background graphics area. Following schematics it always seemed to end at...
  12. Data and address bus questions

    Thanks for the reply. From day one I have been thinking it has something to do in the cpu section of the pcb. The game started acting up one day by freezing up in the middle of play. Turning it off and back on and it would work for a minute or so and then lock up again. A few times of this and...
  13. Data and address bus questions

    Thanks for the replys. I have watched part of the video and it started to lose me so I need to start over and see if it helps. I borrowed a friends o-scope tonight and it is not my clock, it is at 5mhz at the CPU like it should be. So I guess I have at least ruled out a clock issue like I was...
  14. Data and address bus questions

    I have been trying to repair my reactor pcb that I have a thread on and have not really made any progress. I believe it is an addressing problem that further down the line is not allowing an enable pin on a chip (74ls245) to be active (it is high) that is in the addressing and data bus control...
  15. Taito Ice Cold Beer: NOT SO Dead Anymore!

    That sounds exactly what an untested pcb that I bought did on my zekes peak. Seeing that I had a working pcb I swapped my socketed chips to the bad pcb. For mine it turned out to be the chip#8279 (40pin chip) as well as the chip labeled AY-3-8910 (also 40pin chip). I was going to probe them but...
  16. Reactor pcb, crystal reads low on logic probe

    Bumping this up again for some help. Let me start out by saying that some of the time when I probe the board I get different readings based on where the game is when it freezes. Today I decided to check for a clock signal all around the board to the chips that I understand the signals to go to...
  17. Reactor pcb, crystal reads low on logic probe

    Bumping this up for some more help hopefully. I just replaced the chip at B3 which is an address latch. It seemed like the output was not what it should have been but I was wrong apparently. Right from the start of this I noticed that any chip being addressed by address lines 12-15 do not work...
  18. Reactor pcb, crystal reads low on logic probe

    It does not work at all. It is never playable. When you turn it on, it will try to run for about 10 seconds to 1 minute. During that time it may speak wrong do different graphic glitches or just stay on the play screen but nothing is flashing or going through attract. Every now and then it will...
  19. Reactor pcb, crystal reads low on logic probe

    It happens from a cold start. The more I leave it on the quicker it seems to happen. It never works from a cold start, it tries to run with glitches and then will freeze. I have thought of the cold solders. I have looked over the board often, mainly at previous repair work. I will take a little...
  20. Reactor pcb, crystal reads low on logic probe

    Thanks for the reply. The power supply had been previously rebuilt and no burnt connectors. I originally thought power problem when it first happened. I turned up power with no change so I turned it back down to where it had been working. I do not believe it has anything to do with anything in...
