    NBA Jam freeplay??

    If the test switch isn't working its best to resolve that issue. Either replace or fix. There are many benefits to having a working test switch. Much more then just free play. Its worth fixing. Harnesses, headers, sticky buttons. I have had to replace a good amount of those original style...

    NBA Jam freeplay??

    I'd test board at ROMs before turning up if game is booting. More likely a bad connection. Check continuity of switch and harness.

    1999 Black Widow Dart Board Floppy Error

    This is usually whats needed once you get the game to boot into POST, the stage your picture shows. From here once the BIOs is setup and new battery installed you will be able to determine if the rest of the hardware is working as it should. CPU, graphics card, hard drive, exc. Then once you...

    1999 Black Widow Dart Board Floppy Error

    Does this have a USB port where you can install a keyboard? I have fixed a couple of the Arachnid Galaxy units. They needed to have the BIOs reset after battery failure. Basically where it says DEL to setup, you would enter and adjust how the game pcb is booting. I'm sure there is info on...

    Taito Qix Power Supply/RESET Question

    If you're thinking the issue is something slow to charge the only component I could think of is capacitors. Other components like transistors need a certain amount of voltage to switch but its very small in comparison to the duty of a capacitor in most situations. I think you would simply have...

    No. You're concerned with output voltages not wattage.

    Compare the power outputs of both. You can find the Arctic Thunder outputs in the wiring diagram. The power supply outputs should be listed on the webpage of the item. Also confirm it has the proper number of connectors/pinouts but most of these new computer style supplies are very similar.

    Hydro Thunder Help Needed

    I got this game to boot. I ended up buying a untested mother board and diego pcb. Swapped them in one at a time with no change and the exact same behavior. So I knew the boards were probably not the issue. I ended up fooling around with the reset wire and the filter board. That was my...

    Hydro Thunder Help Needed

    Thank you for the suggestion but I have already got this far and replied in regards to my troubleshooting (post #17). Maybe my issue was the USB keyboard. I will find an adapter to PS2.

    Hydro Thunder Help Needed

    I finally made my way back out on location and tested the hydro thunder with the same exact standard PCI-VGA video graphics card as @87 t-66 showed above. Hooked up directly to an external known working monitor and with USB keyboard installed holding and tapping both F2, Esc, and Del on...

    using NON SANCTIONED by Raw Thrills video cards on the older games

    Curious when their cut off date for support is? I've got a good number of older RT games. Oldest is 2008 I believe. And several I know still need fixing and I'll stumble upon a bad graphics card, mother board, DIMM stick, I/O board, exc.

    Arachnid Galaxy 3 Dart Board - No Video Output

    Very good. Thank you for the info. I bet that allowing people to smoke in the bars has helped business overall. I never smoked but remember going to restaurants that had smoking and they always seemed to be slower once VT outlawed it. Especially in a country setting. Lots of small towns...

    Arachnid Galaxy 3 Dart Board - No Video Output

    Talked with Arachnids parts department last night. They won't sell me anything until I sign up for there online service......$400/year. Also my current motherboard is running the USB hub adapter card through the PCI slots not the PCI Express slot. Not sure which I/O cable that you're...
