I'm wondering if someone has the proper fixture (Dimensions) for a big blue's marquee, I want to get an LED setup, but I think if I put in a Neon Tube fixture if someone wants to later on retro-fit it with an actual neon bulb they could. But I'm wondering how long / what type the original...

So I found this manual... https://www.arcade-museum.com/manuals-monitors/Wells-Gardner-27d9200-33d9200.pdf It shows pretty well how it's supposed to work, the issue is I get these glitches in the sync when I go through the RGB Molex KK 10 pin Connector. This is with VGA ...

So to try and both help others and try and solve my own issue, I wanted to A: Make sure I have my info correct B: Try and help others no matter what the code is, and share my understanding thus far. So: First things first... The Address Matters, as if it's failing right off the bat Address...

I was able to get my hands on (2) MK2 Sound boards, with the deal that if I could fix both I could keep one... well... the first one had 3/6 roms missing, and leaking caps. So I purchased and replaced all electrolytic caps, and tried to plug it in. And it didn't work. So I started swapping Gal...

I'm looking to fix up a MK2, it's missing the sound board, hence I'm looking for one, it does not need to be known good, can be unkown, or known bad, I'll do the diagnostics and try and bring it back to life, I just don't have any basis to work from, so having something to start with is what I...

So I got the sound board, with a sticker (Y1 Crystal Bad Replace <1h) so someone had done some diagnostics before I got to it, and found that the crystal was bad. Which it looked like it had got knocked around, and I don't have a function Generator to check if it was still oscillating at...

I got (2 Matching) PC133 Non-ECC Dimm Modules, in the hopes of playing some Battle Operation Simulator, and other games, but I kind of hit a wall. Initially I got this error with a superimposed Japanese Region error, which I went into the System menu and changed, and then that went away and I...

This is to go over, and compare notes and try to help others diagnose 246 Issues. So I have 2 Namco 246 Boards, once came out of a Ridge Racer 5 and Once Came out of a Time Crisis 3 Both Boards seemed to be "Dead" as when I plugged them in via Proper Power from a regulated PC power supply, and...

So TMNT Turtles in Time has a Freeplay hack as I understand it, so you can play without it getting stuck at the red (Raphael) Start screen. But I'm wondering if there is a way to add a single Dollar Bill Validator to add credits to the machine, and then be able to pick any player to start and...

I have the CPS1, 2, and 3 Dark-soft Boards, the question now is with CPS1 being both Mono (Jamma) and Stereo->QSound, If I wanted to take a Big Blue, and have a Jamma Switcher, how would I set that up as far as Jamma, Kick Harness, and Line Level Audio (Qsound) so I could play whatever board /...

I guess I'm a bit behind in this.. I apologize I should have done this sooner. Well I'm a Video Game Veteran, on the software (art) side. I worked on games Such as NFL Blitz and NBA Showtime, working on a lot of Mocap As I still do now, but not for Midway of course. :D I've since those days...

So I wanted to be able to enable / disable free-play regardless of the rom's view on the matter, and since all roms are set to default to play with coins, some people have suggested a button in place of the "Bolt" Next to the coin return. I like the idea in principle, but as another person...

I've been searching and there have been some posts that state that you don't need to change anything on the net-dim to upgrade it from 256 to 512, I don't know if different net-dims have different cuircuit designs, from the pictures I've seen this doesn't seem to be the case. But I have yet to...

So I've searched and couldn't find anything on a monkey ball controller, and I'm trying to see if I can make a Sega Strike Fighter Joystick JVS Controller but that'll be another post. I stand of course on the shoulders of others from people who have shared their knowledge on forums, and on...
