I want to ensure 5v 4amps of stable power coming from the JAMMA edge connector. What is the best way to do this?

Two separate recent transactions where @tonyt76 was the buyer (JAMMAizer) and the seller (UVC Scaler). Zero issues either way.

WIP Never done this and am admittedly pretty bad at reading a schematic, but here goes (nothing). Let's hope I don't kill myself. The Goal: A test bench monitor. SCART socket soldered to a breakout PCB All grounds jumpered together RGB lines: 75Ω resistors terminated to ground 0.1uf...

I just need the retaining bolt actually. But if you have a full lock, I'll swoop that up. Hit me up if you have one.

I'll post pics shortly. This has served me well, but upgrade-itis has gotten the best of me.

Are they the same? Bought a cheap supergun for test bench purposes and am finding that Video Ground and Common Ground have the same connectivity. Is this correct?

@IMAGAMERFOREVER sent the item the following morning after I made payment the night before. He provided me a tracking number after sending it on a Tuesday. It arrived on a Friday. The CPS2 turned out to be a conversion, but we made an arrangement that worked for both of us. Honest dude.

Effectively, you'll get both Killer Instinct games with the OG Killer Instinct 2 conversion kit. You'll get a CF adapter with both game images on two separate CF cards. And you'll get a CPS2 kick harness adapter. I have the OG HDDs too. But don't know if they work. Never bothered to use them...

Looks to be a rescued CPS 1.5 A-board. Swooped up from a Chinese source, intending one to be used for the multi. Surprisingly, it works. But I want to restore it to its former glory: YM2151 has to be replaced Needs a recap HA13001 will need to be replaced All these are easily sourced, but the...

Anyone know the proper ones to use?

Just a personal project for now. Varying wiring across my different cabs poses a problem. So this does a few things to get them all up running the same: Allows for a voltmeter to be added to the harness (duhhh) As these voltmeters are all slightly different, I've added cutouts to allow the...

JAMMAizer was created in Diptrace. I can export to *.brd file in Diptrace. But EasyEDA won't accept the file. According to here, looks like it needs to be resaved in Eagle to make this work. Hoping someone with access to Eagle can re-export the file for me. This is the reference design for...

In my opinion, a PC is the best way to leverage emulation to be able to play old arcade games in a single arcade cab. I am sure others opine differently, but there is tremendous economic value in doing so, so let's examine them: A decommissioned PC costs you nothing. Basically, the PC sitting...

CRT disdain aside, just curious if this comparison ever went down. Were you able to tell the difference @jassin000? With COVID restrictions dying down, would love to see this captured on video if it does happen!

Came in today and looks to be pretty darn clean. The CPU was removed from it which leads me to suspect the CPU was harvested to repair another board. Which means there is more wrong with this board than just a missing CPU. Was going to wash it with Simple Green, but looks to be pretty darn clean...

Has all the SIMM's needed to run all games Has the SCSI2SD ODE I only ask that the potential trade partner sends first. Let me know if you wanna do the trade. Thanks!

I started out with MAME before becoming an arcade snob. I've mastered setting up a MAME box. All my MAME builds hide Windows completely. I boot right into the front end of my choosing and launch games from there. Never have to use a keyboard. Everything is controlled via joystick and push...

Tried to keep it faithful to the original US arcade marquee with the cloudy green background and all. Preview below and link here.
