    Namco Super System 22 Tokyo Wars

    You have bad palette ram chips or a bad C404 custom that is responsible for palette graphics, https://www.arcade-projects.com/threads/namco-system22-ram-error.12135/post-196155. I suggest replacing the video board ram chips at locations 3H, 2H and 1H (for both boards). These are all near custom...

    WTB: 27" Sega IR Bezel

    It won't work. The dimensions are different and won't fit in the cab. Only House of the Dead 3/4 and Ghost Squad pedestal cabs have this bezel. Here is a pic of the type of cab I'm working with with the plastic bezel. You can find more pics of this bezel here...

    I have still not found this item yet and would like to get a Ghost Squad running sometime soon. Anyone have this?

    [FS] Out Zone , Mutant Fighter, Sky Kid , Ghost'n Goblins , Surprise Attack and few more hits !

    The last picture you posted a few days ago, that is an NWK-TR board stack. I can tell because of the sub board on the bottom left corner used for networking. I'm interested in buying but idk a good price check for an untested board stack (and shipping from Romania to the U.S.). This is what...

    In this thread we tube and yoke swap monitors

    So it turns out the factory tube in my Time Crisis 2 actually has a deflection angle of 110° as opposed to 100°. A tube swap for those Orion tubes may be possible. I have measured the yoke as well: Zenith A68AHE00X 27" tube (Wells Gardner K7400) Lh Lv Rh Rv .91 mH 16.1 mH 1.3 ohm 8.3 ohm...

    No graphics on original Chase HQ 2 Sit down Cab

    Also replace capacitors on the old motherboard and video card (as well as their respective fans if necessary). It's a common fault on most PC based arcade hardware.

    In this thread we tube and yoke swap monitors

    It's time I explain my situation: I own a twin Time Crisis 2 with awful tubes (to the point fixing major problems between both chassi didn't improve the image). I have two Orion tubes that came from a later Toshiba made TV I intend on swapping but am a bit unsure if they would be compatible...

    Time Crisis 2 error ram on test

    I'm curious what the graphic glitches look like ingame. Also I leave dip 2 off on all System 23 related games I own (Time Crisis 2 and Motocross Go) for safety reasons so the games pass their self tests without any errors. If you are good at this type of soldering, I would swap the ram chips...

    What will eventually replace the SUN PSU for NAOMI NetDimm users?

    Going to make a quick reply. Would there be an ATX psu that is good for being left on in an arcade environment (around 12 hours a day continuous)? This would be useful for operating those later games running on location (Crazy Taxi, 18 Wheeler, Initial D, House of the Dead 2, Ghost Squad).

    Anyone own the optional communication interface board?

    First off, the board itself isn't very common to find because of the fact only one known game uses this board (I'm sure some of you will figure out soon). Aside from the fact nobody else mentioned this board, the hardware this board consists of is rather interesting for what Taito developed. The...

    war final assault conversion Atari Vegas

    Actually, War Final Assault can run on either a Vegas or Durango CPU board. The fact that Gauntlet Dark Legacy can run on either and Gauntlet Legends can only run on a Vegas CPU board is still correct though. Judging by the pic, it looks like the CPU board is a Durango. It's possible to find a...

    Try reflashing the nvram with a v2 G-Net eeprom chip.

    Namco ES3 not powering on

    Possibly bad motherboard capacitors that need to be replaced.

    Toshiba PF (D29C051) - Purple neck glow with arcing - dead tube?

    They used Zenith curved tubes (which are known for their awful build quality with the electron guns). The picture is most likely going to look better anyway since those Toshiba flat 27" CRTs are probably a better build quality anyway. I also verified the neck connector is the same at least from...

    Silent Hill Arcade Issue

    Can you also take some good pictures of the I/O board? That board could use some documentation pretty badly. The problem is this game originally released using optical guns on a rear projection CRT in 2007. Most games were using IR guns during that time and/or non CRT monitors.

    Toshiba PF (D29C051) - Purple neck glow with arcing - dead tube?

    I hope you someday get into chassis repairs on your own. It wasn't really that difficult to get into (at least for me). My first chassis repairs were two K7400s on my twin Time Crisis 2; one fully recapped and both flybacks replaced (successful repair but sadly the issue ended up being the...

    Toshiba PF (D29C051) - Purple neck glow with arcing - dead tube?

    This comes down to "how exactly did the tube neck in the first place?". It's possible a short somewhere in the chassis pcb or wiring caused the tube (possibly one of the guns) to spike in voltage and neck the tube along with it. It's quite a horrifying situation.

    Namco optical gun shells. These are getting to be quite in demand and are ridiculously difficult to find new now.

    Possible to use a K7400 chassis with a 27" flat tube?

    Both my Time Crisis 2 tubes are becoming weak (due to them using a Zenith tube which are known for their poor quality guns). Both K7400 chassi have been rebuilt and optimized to their best extent (any higher will cause smearing). I'm more on the lines to do a tube swap for now because I found a...
