I have a 12mhz “dash” A-board thet is dead. I have no clock on pin15 on the 68000. Tracking it back, it goes via FB66 to the oscillator. I have no clock on the output of the oscillator either. I do have +5v present on it though. Is it possible for an oscillator to just fail? Anything else...

I’ve flipped the board stack and felt the various Ram chips, nothing feels hot. I’m going to probe the ram in the board, but does this look like A-01 failure?

I Have two b&c sets for SF2:WW There are versions to choose from. (B-11) Street Fighter II (ETC Rev G) 05-22-91 (B-18 Street Fighter II (US Revision E) 02-28-91 The B-11 board is cosmetically nice, but just needed program roms replaced. The B-18 had some pins damaged so I had to straighten...

I'm trying to convert a 9" CRT to a bench test monitor, and unfortunately my plan to RGB mod it doesn't look promising: https://forums.arcade-museum.com/threads/lets-rgb-mod-a-9-tv-for-science.530191/ So i'm looking for a K7000 8-pin (Skinny neck) CR-31 13"/19" chassis to drive it. Hopefully...

Recently discovered this was somewhat coveted by Sega collectors for their “tower of power” setups. I got this at Babbages (game store) where I worked in the 90s. Apparently they’ve commanded $200 in some cases, but I don’t want to feed eBay so I thought someone here might want it. It’s in...

I've a odd situation where I have more A boards than b/c boards. If you have any laying around that you want to be rid of, let me know. Looking for something other than SF2, Magic sword, Forgotten Worlds, Ghouls and Ghosts.

Cruis’n USA pcb working and tested. This board had a failed U52 security chip that causes the sound to stop working. I replaced it with a new GAL from buyICnow and tested it in my cab. All functions, steering, pedal, buttons work as well as sound. I played it for about 15 mins. Popped in a new...

It’s not unprecedented, but I’ve seen a dash a-board with a goldstar branded z80. It doesn’t look as bad as some of the hacked together audio circuits that I’ve seen, but the z80 is odd. I found this blog that showed a long board with a goldstar, so who knows...

Reference the eBay hack conversion thread: Here I picked up a forgotten worlds conversion from the eBay shop with the (cough) improvised audio sections. As expected the sound has stopped working properly. The attract mode sound effects work fine, but as soon as you coin up the audio stops...

I can bore you with a lot of details, but I have a Fully restored zback that currently has a Pandoras box DX 3000 multigame inside. If you have a friend that only wants 1 cab with a ton of games, here it is. The newer DX Pandoras boxes have a much improved interface, with save states and 3-4...

I'm looking to get funds for other projects. I've had this cart for a long time, but I really don't play it that much and I know it would be more appreciated by a collector. This is a very rare MVS tile, it doesn't come up for sale very often. This is a 100% legit cart (see board pics) vs...

Hi, Began when I noticed a member selling a WW to GNG conversion. His was based on a WW 90629B-2 rom board with a B-17 c-board. I had a similar working 90629B-3 board and I asked him for his files, which he kindly sent me. Had buyicnow burn the GAL and Graphics chips, I did the program and...

I'm considering using a riddled TV switcher to put Tekken 2, 3 & tag into my Namco cabinet. The cab uses the onboard amplified audio, using the left channel from Jamma pin 10 and the right channel from the kick harness pin 1. The switcher works by using Jamma pin 10 for audio left and 11 for...

***traded locally For a PC-10 dedicated*** A few months ago I picked up 2 rather rare MVS cabs. The woodgrain 19" cab is an oddity of the SNK MVS line up. Directed towards the Bar/Lounge/Waiting room market, it's woodgrain vinyl look is a bit of a throwback to 80s cabaret cabs. The idea is...

I have a Magic Sword board where the gameplay is missing all text elements, no high score, no bottom information area. Just characters and backgrounds in the main area. Sound works fine. Also missing is the startup copyright text, title screen, & the "winners don't use drugs" screen. The...

So I WAS psyched about a good deal CPS1 Street Fighter 2: World Warrior, until I open the box. Apparently these things are made out of diamonds. it’s totally dead, nothing. Speaker probably bashed around the whole trip. So before i demand a refund, I tried the normal CPS1 troubleshooting...

So I just snagged a WW CPS-1 board on the cheap. I'm interested in the CPS1 multi and I didn't want to use my CPS-1 Dash board. Of course I forgot that the b-17 based C board on WW won't work with the CPS1 multi so i'd have to pickup a new C board as well. In the mean time I was thinking...
