Any idea where I can order this adapter

I'm working on a 484 for a friend and the Juke continuously plays all records in order on the carousel. Another odd issue is if I set the price so you have to pay, and add a credit, after you select a number, the credit doean't count down. I don't know if that is because it is already playing...

Just wanted to show the Chicago Coin Super Flipper I recently got up and running. I did end up buying a board from another collector but I have learned a lot about this game. If you make it out to MGC next weekend in Milwaukee you gotta play this. I couldn't get the monitor completely dialed in...

The Tipperary Ireland plant actually produced a lot of cabinets. It was definitely more than a tax reason. It was a better way to get Atari into the European market. They made the boards here then shipped them to Ireland to put in the cabinets they made locally there. I have seen some other game...

well, first off you can't blame the Guiness smell on it being Irish. Guiness happens to be my right hand man when I'm working on games in the garage. I'll check the serial number tonight and also try to post pictures. The game is kinda rough and I'm nervous to restore it without knowing if its...

I have had a tempest for several years and I am just now getting around to restoring it. Someone mentioned to me once that it looks like an Irish cabinet because of the coin door. Also, in the manual it shows a different slide switch for the test switch, which is what I have. But the data plate...

Anyone know where I can get schematics for a Tele-tennis arcade?

Problem solved. I replaced the surface mount resistor for sync with a 1 k carbon resistor but that still didn't fix the issue. I received in U45 and U47 from Zenomorph and installed U45 and the problem is solved. Thanks for the help!

Update! Zenomorp is sending me U45 and U47. In the meantime I did some more troubleshooting and was able to trace pin p (Sync) of the edge connector back to U45. There is a pull up surface mount resistor between U45 and pin P. I read 34 ohms. Not sure if that is what it should be. So I think I...

I did send him a PM. Without schematics I'm just guessing it would be one of them. I have no idea where else to check on the board for a sync issue.

Yes, the picture rolls both vertically and horizontally, it's just hard to tell in a picture. I do have video but it's too large for here, but anyone who has ever worked on monitors knows what it looks like when a monitor won't sync up. I have verified sync continuity from the UMK3 board to the...

This is definitely not a color issue. It is without a doubt a sync issue, and not a color issue, so I didn't think measuring the color signals for voltage will help. Hers the history. I just bought this, and the guy I bought it from said his friend thought it was a monitor issue. This guy...

I'm now looking for working U45 and U47 IC's if anyone knows where I can get them. Thanks

So I just picked up a UMK3 and I am convinced the Sync from the PCB isn't working. I tried 2 separate monitors and couldn't get the sync to work. Also, only 2 of the 3 LEDs light up. Any thoughts?

pots are good, I looked at them and tested. Connections J-15 and K-S are good. I will be looking at this further tomorrow night. Thanks Guys!
