A few months back I got a deal on a Midway Strike Force with non-working sound. More recently I had an opportunity to buy another one and THAT one ended up also having non-working sounds... same symptoms A lot of times I've been able to revive these with simple stuff like replacing the pin...

Recently I came across this article about a previously undumped prototype for "Power Up Baseball" it's basically Midways attempt at a Baseball version of NBA Jam or NFL Blitz. https://gamehistory.org/powerupbaseball/ The game actually runs on Incredible Technologies 32-bit hardware (used by...

Hey guys I need a VA0 Dreamcast to test some fitment issues with my 3D printed mounts. So I don't care if it's completely dead or if the case is covered in scuffs and scratches.. it just needs to be a VA0 model with the metal heat-pip setup, preferably complete. In-fact if you've got a broken...

Recently I came across this auction: https://www.ebay.com/itm/Fantastic-Journey-pcb-Gokujou-Parodius-Konami-1994-shmup-/254789042037?hash=item3b529c3f75%3Ag%3A1BoAAOSw5ONfvffm&nma=true&si=8bQtV8vlzurnBKMPPOH7WkUJjME%253D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557 This is a USA...

A while back I worked out a drop in RAM replacement on the Midway Y-Unit Arcade hardware. This came up recently in a convo I was having with a friend of mine so I detailed it on my blog: http://solid-orange.com/2051 and I figured I'd repost it here. The original chip on my Y-Unit boards was...

Does anyone know what the original PCB feet or PCB mounts are supposed to look like for the Namco System 1? I've had 3 of these boards pass through my hands and none of them have ever had any sort of PCB feet attached. Looking at the way the board is designed they'd have to be super tall and...

The Arcade community has made some good strides in reviving boards with suicide batteries. Recently I found a few non-volatile RAM replacements for battery backed RAM on non-suicide battery backed PCBs, so I thought it might be useful to start compiling a list of PCBs that use battery backups so...

Whenever Model 2 or 3 conversions come up the biggest problem usually ends up being unclear on the proper jumper configurations. So I've started a spreadsheet to capture this: https://docs.google.com/spreadsheets/d/1X0yhBgxWGy56PX7o1nM0SoOtj4pfSgu5r3gYe_EGfTU/edit?usp=sharing There is still a...

Those of you who follow my projects know that I bough myself an industrial-sized Vacuum Forming machine about a year and a half ago: The Obligatory "Post Your Recent Purchases" Thread I bought this explicitly to attempt to create reproduction part for my Sega Flash Beats Cabinet: Sega Flash...

Post up if you're interested in a Namco NA System Multi by @Hammy (PCB design by @caius Arcade Repairs & Engineering) and specify if you want a "Fully Assembled" multi or a "DIY kit" that you need to solder together yourself. Please be very clear about whether or not you'd like to buy one and...

I'm hoping someone here own an original Gundhara PCB that can help me with some component part numbers and maybe take some photos for me. Primarily I'm trying to find what ICs are used on U2-1, U2-1, U5-1, and U5-2 (the SMD RAM chips on the back edge of the PCB)

@sergiopolog and I started this discussion in the Interest Check thread, and I wanted to move it to it's own dedicated thread so that it doesn't get lost. Why is this important? Because the upcoming CPS1 Multi will need a battery backed C-Board to be installed without some serious soldering...

Recently Darksoft Unveiled the C-Board Requirements for the new CPS1 Multi: TLDR: From further clarifications the idea is that you will need a C-Board with a B-21 Chip (look at the pictures below noticed the "B-21" text on the large black chip). If it's a battery backed B-21 C-Board you'll have...

This might seem like a weird ask but I want to buy 2x Mahjong Harnesses. basically these will have a JAMMA finger board on one end and an edge connector pinned for mahjong with a longer sub-harness for connecting to a mahjong control panel. looks like this: I've been meaning to make some...

I've been hacking around with Taito F2 hardware for a while now. One conversion I've recently complete is converting Ah Eikou no Koshien (a Japanese Baseball Game) into Gun & Frontier (A vertical SHMUP). I wanted to post up a log of this process as I utilized and learned a wide breadth of...

I'm working on a conversion, it's 99% complete but there is an issue with the controls. I think I have a solution but I'm a total 68K noob so I wanted to bounce this off some of the experts here on AP. Overview of the problem: The original hardware for the target game (the game I'm converting...

I'm specifically looking for someone who owns the single board version as I need some info about some of the ICs on it. heck any good high-res photos would be great, but if you have a PCB even better :) this is about the only image I've been able to find which isn't good for much to be...
