    These are from a Satan’s Hallow scan that I cleaned and sectioned off, for visibility sake. I believe these are the same as Tron? Maybe others. @cdjump can you confirm?

    Konami 4 player PSU

    I’ve looked and haven’t found much info. Anyone have a pic of the power supply on a simpsons and how it’s mounted to the lower ventilation hole? Not sure if all Konami 4 player cabs have this hole, but I’m curious how it’s mounted and with or without a metal grate. Thanks

    Cleaned Double Dragon 1 Schematics

    I have spent ample amount of time to clean, correct and mark some IC for ease of reading. Thanks to Doktorzett on YouTube for teaching and posting DD videos while going over the schematics. In an effort to understand the schematics, I thought they needed to be more legible. The boot Rom test...

    Looking for Pantman

    Trying to locate “Pantman”, who was on here at some point and posted on Jammarcade. He created a Wrestlefest diagnostic rom that I’m having issues with. It’s appears to be several years since any activity. Anyone know this person, or a contact for them? Thanks, Kyle

    HD63C09

    I need a CPU for my double dragon. It’s missing.. I’ve seen some on eBay, but are these fake? No one seems to carry them so I’m assuming they stopped production and eBay has fakes. So is my only option a used one? Kyle

    GT Green to Red Power Supply

    I’ve looked, but no answer with this ground was found. Going from a Green GT fore board and Power supply, to a Red GT fore board and power supply. The green board power supply has this ground coming out of the unit and going to the ground block. The red power supply doesn’t have this wire. Is...

    Polo Film Caps

    A couple of questions on Polo Film caps.. - Can I use a higher voltage rated Film cap? I can with an electrolytic capacitor, as long as the farad value stays the same. Didn't know if the same went for Film caps. - Can I use a different dielectric than the original Polypopylene? I'm seeing...

    K7000 Voltage Diagram

    I modified the original K7000 Schematics in the manual and added voltages. These voltages are found in columns on another page of the manual. I took out values and organized some of the lines to de-clutter and clean this up. Diodes, transistor and IC voltages per the manual added. I'm still...

    66.6667 MHz testing

    What is my cheapest option to check the 66.6667 crystal in my GT complete? I have no scope and my cheap logic probe only goes up to 20mhz. Are there other logic probes that can test this high of a MHz? Or is my only path needing a scope? Thanks

    6116 RAM confusion

    Hey everybody- I'm needing a replacement RAM for Wrestlefest. It has a thin V61C16S35L Vitelic RAM that is bad. I've done lots of research and looks like this is a common "6116" RAM. Mouser pulls up several thin 6116, but they have different ns values. Going off the Vitelic data sheet, my...
